The only reason she's as remotely influential to the degree that she has been is because of the stupid fucking chuds who made a game of harassing her. They're the people who made her the face of online feminism. They're the people who shone a spotlight on every little thing she did and put her face on thousands of video thumbnails and her name in thousands of video titles.
Their campaign against her was built on the back of lie after outrageous lie for the sake of pandering to an anti-SJW crowd who had come to see her as the face of the movement, and that in turn led to her taking on a visible role on social media - both to defend herself against the unprecedented wave of harassment and attention she received, and to use what infamy and influence she had gotten to spread her ideals.
Anita Sarkeesian would still have her own fanbase and some degree of popularity without the backlash, but the fact is that she wouldn't be a household name among the terminally online circles who know about her without the Gamergate morons who elevated her to the face of a movement through their behavior. She was targeted because her Kickstarter blew up, sure - for better or for worse she was going to have fans and get attention for what she was doing. But she would never be as relevant as she is today - to the point where topics like this are still popping up on message boards like this - without the gamergaters whose collected disdain for her gave her more of a platform than she ever would have otherwise.
My thoughts on Anita Sarkeesian herself? I don't really care. I don't watch her content, she's not in any of my online media circles, I have no judgements on the content of her character or the content she produces. I understand she fell from grace, and that makes me even less likely to seek her out. I'm not that interested in her as a person.
My thoughts on Anita Sarkeesian as a public figure? The people who hated her the most are the people who made her the most relevant, and I truly believe that the gamergaters who elevated her to such a prominent position despite hating her so much are some of the stupidest motherfuckers on the internet. I fully believe that the proponents of her backlash are the same kinds of people who dropped their Gillette products in the toilet in the wake of that ad, or who (used to) express their discontent with a brand by buying up a bunch of their stock and destroying it on camera as a form of protest. Like, they still got your money and exposure, numbnuts. You're still helping them.
I don't care enough about Anita Sarkeesian as a person or content creator to know or talk much about her. But regardless of whatever the hell her deal is to anyone, I find her fascinating as a public figure, and I doubt I could dislike her more than the people who made her the face of a movement against her will and against the interests of online leftists at the time.
