People are allowed to be critical of entertainment, and that includes comedy. In fact, sometimes you should be critical of things that people brand as "comedy".

Sometimes things are problematic, regardless of their intent as "comedy". And that's normal. Comedy often ages very poorly. Remember all those movies that used rape & sexual assault as a punchline? Should we not be critical of blackface because it's supposed to be "comedy"? Should we turn off our brains because "it's just a joke"?

You're allowed to laugh. Others are allowed to be more critical. Both are valid.

Relax.
