I'm at the point where when I see this stuff and I'm just like "okay".
Literally everything is discrimination anymore. Having a different opinion these days is almost considered hate speech to some of these almost zealot level idiots. I've met some awesome LGTBQ people over the years, just wonderful people to be around regardless of their orientation or what gender they see themselves as. And then there's people like this who view anyone disagreeing with anything they have to say as discrimination. There are radicals and basically at this point hatemongers within any sort of organized groups or movements, so one shouldn't associate all LGTBQ people with this person's thoughts.
The vocal minority tends to ruin things for the rest of them, just look at feminism. I'm a woman, gender equality is important, and just for saying that, some people would be like "you're a feminazi!" because of how many people in places like tumblr say if a man looks at you he wants to rape you, or anything else in their huge anti-men crusade. And if you speak up against third wave feminism as a woman, you're attacked and told that you hate your own gender and you've been brainwashed by men. The moral of the story is people suck, they've always sucked, but they suck especially hard now. Radicals should not be paid attention to, because they paint an ugly image of the rational people in their community/movement.
