He's keeping work & family as much as possible separate by doing this. He doesn't play with women, because twitch, twitch chat etc. do make assumptions and do spread lies and rumors. He obviously doesn't want that in the interest of maintaining his marriage and online character / persona.
By excluding them from his stream he's not fucking keeping the status quo of women not being on equal footing as men, wtf? That's insane. Just look at sodapoppin and look at what happens when he IRL streams, or plays games with a girl. Now he sort of thrives of that so he doesn't care. It's how he keeps his viewers just like reckful etc.
And you know what? Even if it is "durrr indirectly sexist hurrdurr" he still has the right to do it. It's HIS channel, HIS life, HIS marriage and HIS decision. And if you've got a problem with that, you're free to express that but you can't start calling him a sexist and saying he's giving weak excuses.
Also women are still on fucking equal footing like honestly what are you talking about pal? Ninja got big on his own, women can do so too.
Ninja plays with people he likes playing with. Women can do that too.
Ninja says he doesn't want to play with women for his reasons, women can do the same for men.
