Ever notice how all the people who used to live in communist nations are the most rampant anti-communists?
Ask any Russian or Cuban immigrant if they like communism: they will despise the idea 9 times out of 10. They know what it's like to live in it and we know what it's consequences are.
The only people who endorse communism are either people who have never understood what communism really entails or people who are pressured to by another government (China).
Welcome to receiving consequences for your actions!
Your professor may not have taught you this, but you can face negative effects for your actions too. Being 'Antifa' does not mean you have immunity to burn down homes and local businesses.
Justice is blind to all, not just to your enemies.
It's like 2016, but even sweeter.
