Eh, whatever. Let them be who they wanna be (barbie girl! XD sorry, i had to)
Personally i dont even see homosexuality as a lifestyle choice. I feel as though they are just people, so why categorize them?
Now, veganism and vegetarianism are things i feel are lifestyle choices, because they actually are choices. You don't have to avoid meat, but some people choose to. Homosexuals really don't really have much of a choice, because as they say, it's in your DNA. Yes, i am a believer in a gene that gives you a sexual preference.
