To be fair, men would get near the same response. "Stupid bitch slut Ken". The hate is the same, only the names change. The internet is a hateful place with a multitude of people willing to step up and shit on you for expressing any sort of individuality or emotion.
The whole point of the place is anonymity. This enables people to do things they otherwise wouldn't, particularly when it comes to the treatment of others. How have you not noticed this?... Like have you taken 15-20 minutes and actually given this any thought or are you just going off of emotion?
