Well, he likes Watchmen, a story that involves a superhero raping a teammate and murdering a pregnant woman in cold blood (then again, she was only Vietnamese). In the early 80's Moore wrote a Miracleman comic in which his sidekick is raped by other teens, who he punishes with gruesome and graphic deaths. I haven't seen WB complain about that either.
So, as I've said before, I think this is a case of Wondy getting old and, well, doing what old people do best: cry about what young people like.
