First off, comparing race to human sexuality isn't a valid comparison. They are vastly different things. One can see and witness a person's race, but they can't see another person's sexuality. Instead, humans usually find out another human's sexuality by other things a person does. For some, it could be the way they dress, how they talk, etc. which may be hints at a person's sexual orientation. However, until the person either openly admits their preference, or there is some other proof provided, one really never knows.
So what happens now? We have young males who are sexually attracted to other young males. Now we don't have communal showers in the military, at high schools, gyms, and athletic facilities. The reason is because the sexuality of human nudity, which plays into human sexuality, though this varies from culture to culture. I think this, along with gays in the military, to cause huge uproars from both sides.
First, what happens when a gay scout is not bullied, not attacked, but just left alone because the other ten straight scouts want to talk about female based sex stuff and have no desire or want to hear the gay scout talk about male based sex stuff? The gay scout will claim "discrimination," and the media will eat it up because the goal for some is never really equality, it is about forced acceptance and engagement. Radicals demand that straight guys talk about sex stuff with gay guy like it is just another "guy thing." They are trying their hardest to separate sexuality from gender, but that isn't how things work.
Second, back to the shower issue. What happens when we have a known person who is sexually aroused by other males. How are the others who are straight going to feel about that? We don't have coed shower facilities in this country, and in many others, and it has to do with nudity and human sexuality. They are connected, no matter how many liberals want to claim that nudity is some sort of non-sexual state of being. You can't say nudity is a sexual thing during sexual relations, then turn around and claim nudity can't possibly be sexual when a person is naked on a beach, in a shower, bathtub, public park, etc..
