I'm 6'0", 170ish. It doesn't bother me. It's a person. Some are big, some are small, some are men, some are women. Get over it, haters.
In people as in other things, there are some forms I enjoy more than others. I'm not going to hassle someone for what they wear; if it offends me (it doesn't) there are plenty of other places to look, anyway.
Besides, the double standard pointed out is real. "Get out and exercise, but don't make me have to look at you" Puh-leeze. *You* try commuting with an extra 100lbs every day. I know I couldn't.
