No application should allow threats of violence and sedition, PERIOD. I don't know a whole lot of reasonable people who disagree with this. But I do see some people complaining that Parler, an app specifically set up to give neo nazis a home online, which was and continues to be actively used to plot violent overthrow of our democracy (you know, that little coup thing that was televised this past Wednesday that the whole world saw?)
And please, saying you've seen violent posts on Twitter just doesn't make it true. Maybe, maybe not. Report them, and yes, let's hope anyone, from any stripe, planning violence on these platforms is banned. Again, nobody of any reason disagrees with this, certainly not on the left.
No but please, keep defending the Proud Boys and the other scum who used Parler from day 1 as their tool to plot violence, totally out in the open, with zero moderation at all. It's a great look for you.
