Most of what you're hearing is horribly, horribly slanted, if not outright false. Ask yourself why we're supposed to take someone that cries "i'm being harassed!" on faith. Ask yourself why certain prominent individuals have been caught faking harassment directed at themselves.
http://deepfreeze.it - literally every single point of discussion on this site is backed up with a citation, and it provides a very strong, very plausible alternative to the narrative surrounding that movement. I'm not going to say that trolls in there don't exist, but it's not near as significant a component of the group as you've been led to believe.
Not in my personal experience, both of Milo and of Gamergate. Glad to hear you have a different and better experience, but I saw the harassment and thuggery in action.
I guess any self-righteous and simple-minded "cause" like #gamergate is likely to attract trolls and misogynists, but my personal experience on Twitter was that it was mainly backed by thick bigots. Of course, YMMV.
Just the sort of crowd that Milo can manipulate. And in his cynical self-aggrandising universe, dupes are there to be manipulated.
