"what if "gay" and "straight" were switched?" What a convoluted hypothetical, if all of a sudden it switched....well we would head into our species extinction, Homosexuality is an evolutionary dead end making this hypothetical implausible.

Lets look at a more plausible hypothetical, What "IF" there was a cure for homosexuality in the form of a pill, would Homosexual people take the pill?

Note: I know most Homosexual advocates will state that homosexuality is not an 'Illness' or 'disease' to cure, but we already have medication to cure or assist with depression, anxiety, Attention Deficit Disorder, and schizophrenia. All brain related afflictions of chemical imbalances, so why not the potential to cure or assist with Homosexuality which it's self is can be considered a mental affliction, although it's taboo subject.

Again, it's a hypothetical worthy of at least some discussion as it at least is a more plausible situation, I know the film it's self was meant to illustrate to heterosexuals how it would be if the coin was flipped, but the hypothetical word is unrealistic and only goes to show that no matter which side of the coin your on you will be shunned for who you are and what you think, the very least we can do is allow free thought and free speech as means to free discussion with out the negative baggage of silencing those with opposing views which so often happens.

Anyways, my 2 cents, take it as you will.

If love isn't to do with physical attraction (something I agree with you on btw), then don't you need to tell all the straight people that as well? Afterall, if having a relationship is supposed to be about love and not anything else, why shouldn't we all just be bi-asexual? Considering I believe that the majority of people are actually born with bisexual tendencies anyway (look at history and you'll see the percentage of bisexuality was a lot higher, in fact, in some countries such as Japan, the act of loving a man was considered "true love" and loving a woman was just something you did to reproduce), then I think that would work perfectly fine.

Your argument about having so much to learn from the opposite sex implies you don't think there is much to learn from the same sex, something I disagree with strongly. You can learn loads from the same sex just as you can from the opposite sex and the idea that you have to be in a relationship with them in order to learn something seems a bit far fetched to me. I've learnt lots from female friends in the past that I've never dated, about as much as I've learnt from the females that I have dated. I've also learnt loads from my male friends and whilst I have dated one yet, when I do, I'm sure it'll be a learning experience for me.

As to your argument about birth rates decreasing, I have mixed feelings. Earth undeniably is going to have a massive problem with population size and growth in the relatively near future. If making homosexuality mainstream is one way to reduce this problem by reducing the world's population, then I say bring on the homosexuality. There is of course the problem with population's shrinking affecting the economy of the world but if homosexuality was to become the norm in the developed and developing world (the less developed world wouldn't necessarily make an impact because their economies are so small in comparison as to not really matter at this scale) then all the economies would be affected in a similar manner and thus relative to the rest of the world, the economies would be about as strong as they were. (I know that last part is slightly idealistic, there will be problems whilst the process occurs but compared to the problems of overpopulation putting strain on the economies I don't think it will be as bad). Having decreased birth rates will then learn to a food surplus in the countries that's population has shrunk which will allow for higher levels of aid to poorer countries and thus help them develop and reduce world poverty.

Because the reason why we shouldn't be bisexual is because it leads to the other point that was mentioned about needing the oppsoite sex to discover more about ourselves. Female and male are similar, but different in many ways personality wise , feeling, emotions the way they do things.  They compliment each other at certain times, different ssituations brings out something different form the oppsite sex. You won't get the full 100% learning experience from a same sex marriage.  This is even more evident when it comes to raising kids.  That what nakes being a man or wman unique, we have a certain attributes that bring out the best/most of the opposite other. You can be with a man or woman all your life, but the journey won't be the same as being in a straight relationship.  I think we are all born bi sexuals , with no favoring any sex from the beginning. It's what we experience growing up and view from a very young age that determines our choice of being straight, gay, bi. I read somewhere that most people experiment with the same sex when very young, whether they admit or not, as part of them being aware of their hormones, sexual organs etc. i belive most people who think their gay are actually confused bisexuals. The ones who are really gay are the ones that act all  feminine or masculine, for example you have a guy who feels like a girl, and so he gets with another guy who feels the same way about himself, so you end up with two guys who feel feminine going out with each other, when really it should be the feminine getting with the masculine.  Maybe that feminine guy should have got with that lesbian masculine girl. Anyways i think it's wrong people hate on gays. I think the yshould accept it or say nothing, but at the same time  ithink it shouldn't be embraced because i fear for that future where gays dominate and this movie being a reality.

If hetero and homosexuality are seen as equal in society which is what gays want, neither will appear to be dominant in society (although I believe that hetero will always be the dominant one in society due to it being the dominant thing in our society at the moment and thus it will still the be "proper" thing) and as such, there should be an equal number of hetero and homosexuals in society or just lots of bisexuals. This way, people will get to choose for themselves who they want to go out with rather than have one group subtly enforcing their views on the other (even if they don't realise this happens, majority groups nearly always convey a sense of them being "right" due to the fact that they are the norm).

And as to the learning experience, I guess we are going to have to agree to disagree. I personally think the only way to get a "complete" experience as you put it would be to have relationships with both male and females as that way you get to learn what you can from both. However, I still think this an outdated thought process because society is starting to become more and more accepting (there is still a long way to go) of people that have personalities outside of what they should do. At the end of the day, there is no reason for women and men to ~that~ different personality-wise except from the fact that our current society tells them they should be different (ie. girls like pink, men like blue, men are sporty, women are not) so why should you have to have relationships with the opposite sex in order to learn about certain personality aspects?

Why? Every illness you list there causes the person to suffer. The only thing that causes homosexuals to suffer is homophobia. The cure is eradicating homophobia, which we are working on.

Well after having a prostate exam and being exposed to butt hurt i.e. suffered, I can only fear what a penis insize your ass would feel like. 

no, it would actually solve the overpopulation problem because there wouldn't be acidental babies.

virgin women must feel worse than during their first time and that doesn't stop them from trying again and getting used, does it?
