Antifa can be called many things. "Smart" is not one of them.
On Saturday, an Antifa contingent showed up in Newnan, Georgia, to protest a neo-Nazi gathering. (That's right -- for once, Antifa was protesting against actual Nazis.) Only about 30 neo-Nazis showed up, because despite what the media would have you believe, there simply aren't too many left in the entire country.
As usual, Antifa ran afoul of the police. In Georgia, it's illegal to wear a mask in public with a few exceptions. As this wasn't Halloween and they weren't part of a theatrical production, law enforcement told the protestors to remove them. Antifa, being Antifa, refused to comply.
As Huffington Post's Christopher Mathias reports, in an article sympathetic to Antifa's brand of fascism: "Police officers arrived before the rally began and approached a group of about 50 anti-fascist protesters. They demanded the protesters remove their masks or face arrest. The officers -- who wore bulletproof vests and helmets, and carried semi-automatic rifles -- cornered the anti-fascist protesters, then grabbed those who were still masked, tossing them to the ground and handcuffing them."
