I've noticed this trend too, and it's pretty disconcerting. More often than not, I find myself of having to be careful about getting offended when someone disagrees with LBGT individuals. Seeing so many in the LBGT doing this type of thing, it's hard NOT to fall into the "mob effect". I agree: not everyone who agrees with the LBGT community is some homophobic/tranasphobic bigot. There's a lot of decent people that hold those particular views. Heck, even I hold views that would get me labeled as a backwards, sexist, misogynistic jerk that hates women, by many, LBGT or otherwise. It comes with the territory in this generation I suppose: conforming to whatever society is conforming to right now.
Having said that, I draw the line at discrimination, and hypocrisy. When politician tries to base discrimination law because of their personal beliefs, that makes me irritated, but even more so when that same politician is doing things themselves that wouldn't be considered "moral". If a person is going out of their way to call out and damage the LBGT community, then they get busted for adultery, etc. then that is just wrong on so many levels. More people should practice what they preach, especially if they put themselves on a platform.
