That's cool, but I can't stand obese people.  The way they walk around with fat flabbing around, retarded looks on their faces, plain ugliness and the like.
Oh you were born fat?  It's in your genes?  Tough shit, I think it's the same for gays.     You may disagree with the way they are, think they should do something about it, but you aren't them, so shut up and respect them for their choices.
I'm not going to get into an indepth argumentation but you should really examine yourself and your values.  I'm not talking  left/right political ones, I'm talking plain respect.
