Probably because Antifa hide their faces like a bunch of cowards. Also plenty of Antifa members have been arrested, remember the bike lock professor? It's like a sickness with you, you just can't help but spread fake news as much as possible while accusing others of spreading fake news. Maybe someday doctors will find a cure for dumbassery.
Because no one on the far right hides their face? And sure, some Antifa have been arrested for assault and battery and vandalism. How many have been arrested for murder though? How many have been indicted for terrorism charges? The only fake news is you and your rather sad Baghdad Bob impersonation.
