One of the responses I see often to this claim is that calling GamerGate sexist is blaming the entire movement for the actions of a few trolls. After all, anyone can jump on Twitter, throw some horrific abuse at a female game developer and tack on the #GamerGate hashtag. There's no central leadership, no registration. And certainly, the vast majority of GamerGate supporters aren't sending death threats.
I won't dispute that. The issue is that harassment goes way beyond death threats. Condemning death threats is not condemning harassment; that's basic human decency. In fact, far from condemning harassment, many #GamerGaters -- based on Twitter/Reddit responses to me an others, I'd say at least a majority -- are participating in it.
