When "the idea" of Antifa comes to your dressed in black and kills you with a gun, make sure you remember Antifa is just the anti bad guy squad, and also is an idea. Note this idea has its own decentralized insurgency across the US, colors, flags, patches and iconography but it is just an idea, not a paramilitary group like the Rotfrontkämpferbund.
All of the talking heads regurgitating the "just an idea" sentiment received marching orders because they know something is coming. Just like during the summer of love - it wasn't space and opportunity burning down cities, it was Antifa and BLM.
