Just out of curiosity: Which? There are literally hundreds of sports, and I'm sure there are indeed a few. Yet I can instantly name dozens of popular sports where the world's top athletes are almost all men, yet I had to think a bit before being able to name even a single popular sport dominated by women.

Ultimately, I came up with a few sports that I at least believe that they are dominated by women. But every one of them turned out to be a sport that is to some extent about looking graceful, where the scores are not determined by objective, measureable facts, but by judges giving subjective scores (aerobics, synchronous swimming, dancing etc.). Sports that hardly any man is even interested in.

So you support having no professional female athletes in that league ever?

yes because i believe that even 2000 years ago people were as open minded as they are now.

OK, it was some studies that I saw saying that women had a higher pain tolerance and a quicker reaction time, but now doing some more research I've come across conflicting reports, so I don't know which is true.

Well, this is getting slightly off-topic, but the hypothetical society I was referring to where there is almost no sexism would have to be vastly different from this one. I support a system without currency, so there wouldn't be such a thing as professionals in the modern sense.

Have a dick? Go in the men's room.
No dick? Go in the women's.
Have a dick but gee golly you really feel like you shouldn't? Well until it's removed, use the restroom for people with a penis. Same goes for those with no penisbut really really feel like God made them wrong. Use the girls room until you get that pecker.

Seems extremely simple. I'll never understand the need to make so many uncomfortable to appease so few.

This is talking about schools, though. The age in the U.S. needed to get surgery is 18, so even if they wanted to get the surgery they couldn't:

Even concering adults, it is still very expensive, meaning that many people who would want to have surgery financially cannot do it:

I personally just think it should be if you look like a dude, use the men's bathroom.

If you look like a woman, use the woman's bathroom.

I don't even see why this is "less traditional". If a young boy sees someone who basically looks like a woman come into the men's bathroom, isn't that also going to be confusing for them?

People are really pushing things too far.

So call me whatever you want.

You were born a man, therefore you are a man. Same goes if you were born a woman.

Simply put, I think people are insecure and arrogant. Transgender as a whole, is too much. Why someone has to go all the way to alter something already set in stone is beyond me. Not to mention changing birth cerfticates. If this isn't related to self esteem issues then I have no idea why. 

There are things you cannot change. You just have to accept it. Now I'm not talking about homosexuality. That's a different tangent.

I'm not making a statement here, but gender is commonly defined to be much more broad then sex and includes societal views of the characteristics of the masculine, feminine and in between along with identity.
