That's a tough right/wrong question, especially since I think it's human nature to respond the way you're responding. But just because something is human nature doesn't make it right.

I do the same thing, to the extent that I can, with various groups. I'm actually a lesbian, but I don't generally fool with other gays and lesbians because my experience is they expect you to be stereotypical and it's hard to fit in or be accepted if you're not. A lot of LGBT spaces/environments are also just too culturally white for me, personally, and I'm not white. So, that's more awkwardness and not fitting in on top of not being stereotypical enough. That's just one example--there are many others.

Trying to lose weight and eat better is hard when you're around other big people who don't have that same mindset because they're still doing things you're trying not to do and they don't really respect what you're trying to do enough to not tempt you. And I'm not saying they should change; it's all their choice. And I never give thin people a pass or act like they're more accepting, because the truth is that before you started on this path they were probably judging you similarly to how you're judging the overweight people you're talking about, and will continue to judge your weight and discipline to some degree until you finally meet their standards. They just are not sharing these judgments with you.

So, that's one thing to understand about this--thin people suck just as much as overweight people, just in a different way. And that's really how I look at people--we're all azzes, just some of us are similarly based on what groups we belong to whereas others are a different type of azz depending on what group(s) they belong to. I guess this is at least partially why I don't trust people and don't really have any friends. But I'm good with that.

I guess my point is it's just people, not only specific groups of people.
