Dunno.

EDIT: Edited this comment years later because it was a very, very stupid comment to make. I apologize.

Being the norm doesn't imply right or wrong. It just identifies what is the majority. People in general are afraid of what is different or unnatural. That human reaction is also reinforced by the two biggest social systems in the world, religion and science. Religion teaches that we were created to procreate and populate the Earth. Science theorizes that the fundamental purpose of life is to pass on our genetic code through reproduction and survive as a species for as long as possible.

... ... you probably never heared for a term "hermaphrodite". For example all Clownfish are male, and then the biggest fish in group becomes female, Parrotfish are all born as females etc.

And intersexuality is not that uncommon among humnas either...

Not sure why this seems like a silly argument to you. If the majority of any population wasn't interested in undertaking an action that carries the chance to produce offspring (regardless of whether producing offspring is the main intention or not), that species probably wouldn't be in existence for long.

It doesnt seem silly, hence the facepalming.

Well, didnt read all the posts except the opening... but still...

Because thats how the human race reproduces? No that doesnt make it right to hate on gay people but it is what considered the norm as thats what has kept the human race alive for the last million years. But beings evolve, and I am happy for a gay person to openly be so and am happy to say im close friends with a few who are. But still, it isnt the normal and if you look into other species that exist you would struggle to find many who arent hetrosexual and only procreate for the purpose of creation. Humans have turned procreation into a pleasure as well as a need to continue existence (not saying thats a bad thing!).

Perhaps in a few more years time gay sex will also be considered the norm and possibly even a way to continue reprocreation! time will tell as evolution will

...maybe I'm taking something out of context then. It seems like your post is facepalming in response to that argument.

EDIT: Never mind I just remembered that was in the OP post. I feel silly.

Because the greatest desire and reason for life to exist is to reproduce and create offspring. Heterosexual couples are the only ones can do that.

However that does not make it right to hate on Homosexuals or anyone else. Everyone is entitled to their opinions and life choices

This isn't true. In addition to the whole categories of animals that exhibit hermaphroditism (simultaneously, or changing between sexes sequentially), there are plenty of animals that engage in sexual behaviour for social or entertainment reasons including self-stimulation, homosexuality, and mating behaviour out of season where pregnancy is not possible.

Same reason most people are right handed. They are just born and wired that way.

Do you think left handed people should be killed? If no, then no different for gay people.

Plus, many of them are Fabulous! You aren't against Fabulous things are you?
