Even if a certain religion is against homosexuality, it does in no way mean that people who disagree with homosexuality on religious/moral grounds need to act like jerks to those that are gay. One can disagree with what someone does (for ANY reason, it is a free country) without despising them or acting "phobic" about it.
Not everyone who is against, say, gay marriage is adamantly opposed to the continued existence of gay people. It comes down to that old "hate the sin, not the sinner" kind of mentality. You can disapprove of what somebody does without hating the individual on some personal level. I mean, gay people have other characteristics that define them. Being gay might be a part of what makes them up, but it is not their whole identity. Besides, anyone who defines themselves solely by their gender or sexual orientation probably has bigger problems than a small minority of "phobic" individuals who dislike what he/she does.
I mean, there's perceived "racism" and then there's actual racism (as in, genuine hatred of another person based on skin color), just like there's perceived homophobia (person who doesn't agree with the gay lifestyle for whatever reason) contrasted with true homophobia (genuine hatred of another person based solely on sexual orientation.) Just as it's important not to make blanket statements about gay folks, I think it's equally important for homosexuals not to view every little disagreement they have with somebody as an example of deep-seated homophobia or hatred.
I mean, there is the little matter of how if everyone were gay, it would be virtually impossible to continue the species. Not using that argument, just throwing it out there.
Anyway, that's my two cents. Some part of me thinks this whole thing might be less of an issue if the gay community (that I've been exposed to, anyhow) weren't so confrontational and pushy with their lifestyle. In random classes I've had people I didn't know tell me they were gay. What does it matter? What do I care? Why do I need to know? Sometimes it feels like some (not all) gay people are acting like militant feminists or something, where I not only must acknowledge their shoehorned-in and completely irrelevant sexuality choice, but agree with them completely about everything. Bah. But that's just some people.
