During a recent anti-police protest in Portland, an Antifa member was punched in the face twice by a counter protester. That's when irony kicked in.
The Antifa member actually complained to the police that they wanted to have the other guy arrested.The police were happy to arrest the guy, but that act would entail the Antifa member revealing their identity to the police. Because, after all, you can't file a police report if you don't identify yourself.
Naturally, the Antifa extremist was a bit confused by the news.
