If my rant about UW wasn't enough, dr24hours has a great post on the worship of brilliance and how it enables abusers like Katze.
It seems to be human nature to condone the abuses of the powerful and gifted in order to bask in their glory (hence all the "shocking" stories of abuse from athletes, artists, actors, politician, the superrich, star PIs, etc). Dr24hours is absolutely correct that if we don't excuse the first unacceptable behaviors, future abuses could possibly be avoided. No one is so irreplaceable, so talented, or thinks so differently that they can't be expected to treat fellow human beings with the respect and civility they deserve, and held to that standard. At the very least, we need to stop hiding and accepting abusive behaviors no matter how much we like the abuser or desire the use of their talents.
