From this question:

Is it okay for guys to criticize or make fun of a girl with comparatively more body hair?

The top answer is:

"It's never ok to make fun of anyone about anything. Don't be an asshole."

Isn't this a very black and white approach to a shades of grey subject? Much of comedy involves people poking fun of themselves, their friends, family, other people, at their behaviors, quirks, etc etc. The blanket statement that no one should every make fun of anyone for anything seems counter to almost all evidence.
