I say the complete opposite. What's one nice thing about this place vis a vis mlw is the fact JMT said at the outset he wasn't going to be looking over everybody's shoulder and sending people to the penalty box if they weren't right wing enough, such as CA does. It has had ample opportunity to fall into mlw mode and it hasn't, thankfully, and likely won't. Many of the folks here, came from there, for reasons just outlined.
Generally speaking it seems people who aren't alt. right idiots are capable of moderating themselves.
People here were complete a-holes to Argus and Rue, it wasn't moderated properly, and now they don't post here. If you guys want an echo-chamber, congrats.
