There has to be something specific to white racial identity that creates the kind of defensiveness on display.
Like, I'm straight. I've got that going for me. There is literally nothing an LGBT person has said about how oppressive, apathetic, and even outright harmful all straight people are that has caused me any undue stress. Like Louis CK said, "You can't even hurt my feelings." At the end of the day, I live in a world that values heterosexuality over other identities. Generalizations about my majority status just don't bother me, because I get the luxury of ignoring the complaints or not taking it upon myself to address them. I can shield myself with the status quo, because the status quo is all that matters. It's so fucking easy and stress-free to be part of what's "normal."
This doesn't undermine my struggle either. My mom has degenerate bone disease too, Offended Poster, along with disc issues and carpal tunnel, basically disabling her from working. My biological dad died a few years ago and threw us into near-financial ruin. I help out with my mom's issues dutifully and I healthily moved on from my father. It's life. Ultimately, I wouldn't use these struggles to deflect from the generalization straight people have it good (on the basis of being straight in situations where it matters, which is the implied half of said generalization), because they frankly don't have anything to do with the argument being made. That status quo is always gonna be there to shield me from having to face any more problems than I already have to. I didn't have to deal with being LGBT in an anti-LGBT society on top of my father dying, and I can't imagine what that's like for the people who do.
tl;dr-- perspective por favor?
