My stance:
If she's wrong, explain how she's wrong. People who care will listen. People who don't don't matter. If it turns out there are a lot of good arguments to make about how she's wrong, she slips away into oblivion, ignored like every other flash in the pan YouTuber trying to get their voice out there.
Turning it into a witch hunt destroys the conversation. It's no longer about whether she's right or wrong, it's about her being a liar, a fraud and a con artist. People who care don't actually get an explanation as to why she's wrong (if she even is wrong), and people who don't care begin to care because they see someone being attacked for expressing a point of view. She gains more fame, fortune, and influence as a result of this new, completely irrelevant narrative, and nobody can even talk about whether she's right or wrong because any discussion devolves into shit that has nothing to do with her actual work.
Let me put it this way: Let's say Sarkeesian actually IS a liar, a fraud, and a con artist. If she's right about everything she says, what difference does any of that make? Her point would stand regardless of how evil a person she is. If she's NOT right about everything she says, then isn't that more relevant than any supposed underlying reason why she isn't? You can't prove someone's lying, but you CAN prove when they're wrong, so wouldn't focusing on the latter make the former irrelevant? You don't convince people someone is a liar by calling them a liar, you convince them by explaining the lie. So far, everything that has been considered a "lie" has been subjectively interpreted as such and does not stand up under further scrutiny, just like the justifications for the "fraud" and "con artist" labels.
If you actually gave a fraction of a shit about the "damage" Sarkeesian could do (to games, to society, whatever), you'd calmly and rationally explain what she gets wrong and how, and you would completely ignore any and all talk about her personally. But you don't care about that. You only care about having a bad guy to shit on. You wanted a war so you created one. I know I'm not getting through here, but I take immense satisfaction from knowing that you are being made aware of how counterproductive and ignorant your witch hunt is. Go ahead, have your fun! You're a joke. You can pretend I'm the crazy one all you like (I know you will), but I've been the only one speaking rationally here (actually, to be fair, Quaid has too). You've created a self-perpetuating circle of non-logic that shields itself from any outside influence. Your bubble is mighty, I'll give you that, but it's still just a bubble.
