If you'd been paying any attention, you'd note she was forced to shut down comments on a few of her videos because the sheer amount of harassment she was getting made any kind of discussion absolutely impossible. If you've made yourself the number 1 target of hate and threats for daring to critique sexism in games, why leave channels open to yet more harassment? The trolls don't let anyone debate her points in good faith. Their spew overrides all others. No point in giving them a stage. Continual harassment like that affects people you know? I've seen far too many bloggers who discussed sexism leave the sphere of discussion all together because the harassment was causing them too much stress, depression, hell, even suicidal thoughts. It can get bad. I blame her not one bit for seeking to limit that sort of toxicity.
