Yeah, I know what you mean about fat shaming and commenting on looks in general. I have done both.
I'll draw the line when it comes to an actual disorder like Ed's Klippel Feil syndrome (KFS). Comment on his greasy hair, his face, his grossness but having a bone disorder that he was probably made fun of growing up I can't do.
Then again, if I go through my comments, I've probably made fun of things no one can help, so I should shut it. 🙂
