I don’t care when my “heroes” do fucked up stuff to an extent because I don’t expect those I think of as awesome in some way to be amazing in all ways. No human can be that. It’s not a condition that they are 24/7 saints for me to think they’re great.
Obviously, some behaviors are intolerable. But particularly for artists, they often swim against the current. It’s difficult — nearly impossible — for that to be true in just the area where they make great art.
Seems not so difficult to understand to me.
