i really dont like being asked “has [celebrity/idol] done anything problematic????”
of course they have. you are not going to find a non-problematic person. now you can get specific and ask “have they done anything racist, transphobic, ableist etc”. but “problematic” is such a vague (and sometimes completely useless) term
what you can tolerate is based on your own experience & morals and also i feel like you should take microagressions vs violently harmful offenses into account.
