It’s very hard to draw the line. I see your point I just find it intractable.
For example what if I told you that one of the executive producers of your favorite movie is a horrible felon? What if it was the editor ? Do you background check all of the contributors?
It also seems to me that people who achieved great things were either deeply traumatized or really disturbing individuals. A regular 9-5er who is an excellent family member, friend and has great morals rarely achieves greatness. I guess it really begs the question is it worth it?
I think historically we relied on the great work these horrible folks and conveniently scrubbed their horrible backgrounds.
