I've been listening to the 'how did this happen' coverage and no-one is offering up as part of the explanation that he was a big fan of 'brutal pornography.'
If men wank off to women being brutalised that is inevitably going to lead to some of those men going to act out the violent fantasies which porn has now hardwired into their neural pathways as arousing.
If blatantly violent racist films were mainstream no-one would be surprised that racism increased, and I am sure all commentators would feel comfortable making this point.
But when sexualised violence against women in mainstream why are we pretending this isn't one of the contributory factors to brutal crimes like this?
