Antifa can just do what it likes, as it is so “cool” with the establishment. Follow the links in the articles below, and watch the coverage via videos as these champions of the Left bash fascists, and anyone else like old people.

     Let’s see what we have here. Antifa attacking conservatives boarding a bus, spraying mace, hitting, kicking, breaking a bus window and spraying mace, hitting an old guy, death threats. They are busy! We do not know at the time of writing who has been arrested, but given previous treatments by the system, probably the people arrested were those bashed. In the future if protests are still permitted, I expect rifles to be handed out so that conservatives and Trump supporters can be shot, just like in the film, The Hunt! After all, that is where this is going.  Clearly, the Proud Boys need to abandon street protests because the system will never protect them, and just uses them as punching bags. If this took place in a country which still had national pride, like China, the police would deal with those committing acts of violence using giant electric forks, something out of Star Wars:

“Hong Kong protesters may be in for an electrifying experience after Chinese riot police were pictured training with 'terrifying giant fork devices' designed to subdue humans and pin them to the ground, according to the Mirror. While unconfirmed, the 8-foot poles with U-shaped prongs are believed to be able to deliver an electric shock. The protests, now in their 11th week, have been alternating between the streets, subways, and airports of Hong Kong. While largely peaceful, there is a growing contingent of activists using violence and property destruction to protest the government, resulting in police tear gassings and beatings.”
