Yes, perfectly fine. Jordan Peterson banned for being "far right" (he is nothing like that, for decades warned about the rise of fascism and nazism). And far left groups are allowed to perform violent acts and recruit people.

All these liberal groups are waking up dark and powerful forces that have been dormant. They are delusional thinking it's something they will be able to control. Same applies with republicans feeding the Tea Party and all that. When anger rises it doesn't stop until there's a lot of blood.
