I tend not to believe that women receive repeated threats of violent rape at chess congresses.
'Couldn't agree more with Ian Kingston's comments. There is also the common phenomenon of victim-blaming - "well if only she had done (x) or (y)....."
Chess as a whole really doesn't take this anywhere near seriously enough; it's a big cultural issue for the game, which is generally just shrugged off or ignored.
Nor do I see how writing blog posts saying that women are abused, harrassed ,subjected to sexist comments and threatened if they play chess will attract women into chess. Of course, I may be wrong.
Perhaps lots of girls read that blog post linked to in the opening post and decided they wanted to become chess players.
