Like the kind of political YouTuber that doesn't actually know what they're talking about.

That’s pretty accurate. She claims to be left wing, and a fan of Bernie Sanders but she frequently repeats alt-right talking points and conspiracy theories. She does a lot of that thing that a lot of right-wing online personalities do in paying lip service towards being a centrist “I MaKe FuN oF bOtH sIdEs”, but really ending up making the right look far more reasonable than the left the majority of the time. She’s also good friends with the conservative pick-me YouTuber Blaire White.

She became popular around the time of gamergate largely (imo) because she says a lot of the things those types like — makes a lot of videos ridiculing feminists etc — and is a somewhat conventionally attractive woman. So gamers^TM can convince themselves they don’t hate all women and all women don’t hate them because here’s one who agrees with them and “she [supposedly] isn’t even right wing”.
