In short, no.
I beg to differ.
Claiming that you are a homosexual, by definition, informs everyone around you that you are attracted to and prefer sexual relationships with members of your same sex (the word "gender" is a politically loaded term and I refuse to use it). Otherwise, how would anyone know that you are "gay," save for the really effeminate men or truly butch women?
Having said that, I completely agree that "gays" and "lesbians" should have same rights as everyone else. I do not think that it is the government's place to regulate the actions of two or more adults entered into consentingly.
