No. Firstly, I'm going to ignore Troll's for purpose of this repsonse. (Yeah, the trolls are smurfing troutty, but everyone with any semblance of clout on the internet gets those in droves.) People dislike Anita because of how nonsensical her statements are. You need only look at her dissection of hit man to realize this. The game penalizes you for killing innocents (You know, like all those strippers you see being killed in the video she that she claims the game in question encourages you to kill) to see how, at best, disingenuous she is being in her critique.
I think that this sort of argument would hold more water if she had not been completely torn to pieces before she'd made any videos. There was no critique made. There were no videos with generalising statements about video games. There was an idea for a video series.

So why did people hate her then? What did she do when making her Kickstarter that deserved the level of vitriol she got?

She suggested that video games might have an issue with female representation. Simple as that.
