I actually did, because I find that as stupid as mocking him for his race, skin color, height or haircut. I'm perfectly ok with calling him a thief, a liar, an idiot, and everything else related to what he did; but his body weight or any other physical characteristic should have no relation at all to this.

Sadly, it seems that when people hate someone, their brain automatically shuts down and they just start firing words at random.
