From the Guardian article on this matter:
http://www.theguardian.com/books/2015/mar/17/dc-comics-pull-batgirl-joker-cover-after-protests
“was now not going to run at the artists request and said that there had been ‘threats of violence and harassment’ over the cover”
So now the Feminazis are emulating the Islamonazis. Threating violent attacks over comic book drawings.
Actually in this case, the death threats were being made against people who objected to the cover, gamergate style.
