GamerGate - That Mirai says stuff

Huh… Context would have been nice, OP.

Basically, he started to get pissy over the DontDateSJWs tag saying it was sexist, and accusing people of being misogynists, before going on a pretty shitty attack on @CultofVivian, the Vivian cosplayer whose made a few videos. Ironically, he helped prove #DontDateSJWs isn't sexist, by being the perfect male example of an SJW you shouldn't date.
