I really believe that the Left is using this as a catch all term for all Conservative online communities, just like this one. To be honest I had not even heard of this until a couple of months ago and had to look it up. I think it’s just another placeholder name to describe online “deplorables” designed to be a counter to the growing conservative online dialogue. Amazing what happens when people start seeing shadow banning happen against them and their friends from the mainstream social media sites.
