Large people don't bother me at all.
What annoys me is the several overweight in my workplace that talk about how they really need to lose weight, talk about how uncomfortable they feel, talk about their new diet each week, talk about their new exercise class, etc, but haven't actually lost anything in the 5 years I've been working here.
One or the other for me, shut up and do it or just stuff your face and say 'meh, I'm fat, deal with it'.
But I have a simplistic view on stuff.
