I disagree, there is a real and significant difference between places with a few outliers that spew hateful awful rhetoric and places that primarily serve allow people to do that. And what does "leave the reservation" actually mean? Pick twitter or reddit - they have lots of people who just want to express ideas, share their views with similar people, but there are also some on there who want to threaten and express a desire to kill those they don't like. On reddit and twitter that will (eventually) get you banned.

I'm free to disagree with the govt, with the political views of any politician, to wish embarrassment for a celebrity, or financial ruin of a business person I don't like. But saying I was xyz to die, or someone to be attacked, or all people like whatever to perish, that's a different thing.
