This is literally one of the most offensive pieces of writing I've seen in a really long time. 
Beyond the absolute garbage about women "making" men have sexual thoughts with their clothing and men being essentially violence driven beings, the idea that pre-marital sex being more commen means that consent is assumed is insane. 

"she created the enhanced risk in the first place since in an age of more casual sex, the male is assuming consent."

Ummmm.....just NO. There is no situation where consent for sex is assumed because you went in a room. The statement that a woman should be prepared to physically fight and scream to let a man know she isn't just giving her consent by being a woman wearing normal clothing is insane.
