I, myself, have been wondering where the "free speech" crowd is this week. A common theme I see here is outrage about censorship by private companies. In the last 4 years, we've seen Trump railing against the press, encouraging people to assault members of the press, etc. In the last 4 days, we've seen members of the press getting maimed, falsely arrested, and assaulted by the police. This is overt suppression of the press by the government, plain and simple violations of our constitution (and quite relevant to this story). This kind of treatment of the press is something that's been used as a partial justification to invade other countries in my lifetime -- that it's happening in the US with hardly any commentary by the "free speech" advocates is a great disappointment to me.
But the "reactionary" crowd is still here -- looking at their patterns of posting on [1], it looks almost tailored to get the story flagged (accounts got banned, but that page only lasted on the front page for a few good minutes). The truth of the matter is that folks are uncomfortable discussing race, because our community has internalized a lot racism. Discussing our society's painfully visible race inequity is "flamebait" because racists gonna show up and drag the conversation down.
