It's extremely concerning that Antifa killed one teenager and grievously wounded another after firing upon their vehicle in the largest city in the PNW and no one in the media is talking about it. If it were a compound of white nationalists there would be no end to the coverage.
Not really how it works. Neither antifa nor BLM have recognized representatives to take credit in the first place. You can just go out and do antifa type stuff like patrolling an autonomous zone and you count as antifa until someone ejects you.
