I call bullshit. It gives him tons more advertisement as an anti-homo fundamentalist who is hated rather than considered for the candidacy. Check the like/dislike ratio on the video, mate. The more people who see it, the more who loathe it.
Being open about one's sexuality doesn't mean dancing on a parade float in the military barracks and trying to fuck all the other dudes in the showers. It means when your comrades are discussing their girlfriends and wives back home and ask you, "So, you got anyone special back home?" you don't have to say, "Uhhh ... no" and lie about yourself. You should be free to say "yes, I have a boyfriend" or "yes, I have a husband and two kids and a dog" or "yeah I've got a few dudes I go around with". No different to a straight soldier saying "I have a girlfriend" or "I have a wife and two kids and a dog" or "I've got a few chicks I go around with". I realise nobody would ever really phrase the latter like that, but I'm just making the point. There's really no difference between any of those, and if the case is that heteros can say that and it's perfectly normal and okay but homos can't because they're gay and shouldn't need to be so open about it, then that would be bigotry.
I think Katie is right, and I don't mean to generalise like this and I know it doesn't apply in all cases, but I think it's easy if you're heterosexual to take for granted how much of a non-event it is if a man is in a social situation or meeting new people and says something like, "Oh, you're from France? So is my girlfriend." Conversely, to say "so is my boyfriend" in that same sentence invites anything from mild surprise and/or a flurry of polite or friendly questions, through to comments of "I wouldn't have picked that" or looks of disapproval and disgust, total awkwardness, people screwing up their faces in you, shaking their heads, refusing to shake your hand or if you're revealed as a homo mid-handshake, dropping your hand in disgust and walking away. (That's assuming relatively polite company, ignoring actual problems like homos being threatened, abused, bullied, bashed, and in many countries, imprisoned, beaten or killed.) Anyway, in most situations it is much easier for heteros to mention their significant other and have conversation continue normally than for homos to do the same thing. The amount of times I've mentioned my boyfriend with new work colleagues or friends of friends only to have them be all "OMG DID YOU JUST COME OUT TO ME" is ridiculous. I'm not coming out of anything; I'm completely open about being homosexual.
Anyway, TL;DR version: DADT's repeal was absolutely important, because it means homos can be themselves and talk about their loved ones and lives back home freely, IN THE SAME WAY THAT (MANY) HETEROS DO WITHOUT EVEN NOTICING.
The Rick Perry video contains very thinly-veiled anti-gay sentiment, period. However, I do agree with you, I don't like the Christian or anything-else bashing, either. There shouldn't be this discrimination, either positive or negative. The opportunities and dignities of the world should be no different whether you are homosexual or a Christian, and of course, it should be pointed out that those two groups are not mutually exclusive; there are loads of homosexual Christians. Freedom encompasses both sexuality and religion, and as long is nobody is being hurt or threatened with either of those, they ought to be protected.
Well said, thank you.
