HAve you met many angsty teens?
What is happening here is of course that what she says directly provokes and annoys that subset of society who will react like that.
That is, teens.
And I am sure she knows it, anyone who thinks about it knows it, and it is common, and means little.
Of course she is not addressing that, she is trying to use that brush to paint 'people in tech', ie: people working there. very few of those are angsty teens.
Really, pick pretty much ANY subject, it would not be hard to get a bunch of nasty responses in an online forum - and she is playing that game, a lot of what she claims could easily be considered trolling (for example presenting paths of play not required or even sensible in games as the main intention of the game just because they paint the game as anti women).
Is she right to involve the police, etc when someone starts saying things this stupid? quite possibly yes.
Is she right to claim this defines an entire gender? dont be ridiculous. THAT is sexist, against men, as she quite clearly is herself.
Which is a pity, that she obviously believes that reverse sexism (by labeling the majority of men to be akin to the worst examples she can find) is good.
