You’d think that being called a terrorist would be worse. However, I have read a lot that child-like insults actually hurt more than mature ones. We established them when we were children, so they’ve been with us longer and carry more emotional weight. So it’s technically more effective to call someone buttface instead of shithead.
Just look at their commander-in-cheetodust and his tendency to call his opponents names like “Sleepy Joe,” “Crazy Nancy,” or “Lying Kamala.”
