It's a good thing to create an enviroment that is safe from 4chan-style brigading, yes. >Is it really no longer possible to have conversations happen between folks that disagree, At this point? No -because neither side can agree on common references; the left get their news from one set of news outlets and the far right get their news from qanon or whatever facebook fringe groups. It's impossible to have a conversation if you cannot even agree on basic language or common references. With their being fewer and fewer genuinely left-of-center outlets it becomes necessary for people to be able to build enclaves that won't be shitposted into oblivion (see also: reddit with the_donald and other brigading subs)
