It's not about a moral stance, or a cultural difference though, is it, it's about basic human rights.
"but the gays are ok as long as they don't act gay" isn't really a great argument is it - would you be happy as a heterosexual person to live in a country where you weren't able to have a relationship, talk about your relationships, have any kind of family/friend/colleague discussion about your relationship? Where you had to keep it hidden or have a sham relationship with someone you weren't remotely interested in just so you didn't go to prison or get thrown off a building? Where how you felt every single day was universally thought of as perverse and something that the rest of the community needed to be protected from? Just because of who you love, who is another consenting adult?
Like the previous poster said, have you ever tried to go on holiday with your partner and not appear as a couple, or experienced people scrutinising you because they want to know what the nature of your relationship is?
Everyone on this thread is fully able to go out and protest women's rights and slave labour - those that are saying these should be the issue at the forefront, what have you physically actively done to protest these things? If you don't like the fact that LGBT lobby has a loud voice then get out there and add yours to the cause you want to champion - it's not a pie, if one protest has a big slice, the other issues don't get smaller slices.
And for the poster saying it's all about white men wanting anal sex or whatever you said - seriously, grow up.
