If they have the wrong attitude, why not criticize that?
In an ideal world, sure that would be the correct thing to do. But the reality is that, we as human beings, enjoy body shaming people who we disagree with. It's why it's fun to body shame people like Trump or calling people like Ben Shapiro a Manlet midget incel loser with a useless micropenis.
Well I commend you for defending monsters from body shaming
