Louis C. K.
I've never watched his shows or otherwise been a fan, so the very credible sounding accusations against him didn't surprise and dismay me in the same way learning about Bill Cosby did. It seems that Louis C. K. is connected with practically everybody in comedy, as friend, former writer, or mentor. Is it really possible that none of these people had a clue what was going on? The rumors have been out there for some time, and the victims apparently were telling friends, colleagues, and others long before they were interviewed by the New York Times.
I think that Jon Stewart, Jerry Seinfeld, Aziz Ansari and practically every night time host you ever heard of have some explaining to do. So far nearly all of them have kept their silence or been evasive or worse. Louis C. K. was Stephen Colbert's first boss in comedy and so far has been practically the only male to speak out at all.
A lot of these creeps are going to escape without any legal consequences, but at least they deserve public condemnation and being kicked off the airways.
