If the radical left take over the USA, they will build the wall bigger and with minefields and guns to keep the people IN. Just like the "antifascist protection wall" in Germany where the communist shot their own people in the back for fleeing their left wing 'paradise'.
This is a valid strategy anyway. Push for removal of liberal CEO's and professors to be replace by blacks. Someone should start a website: kickoutwhitepriviledge.com Where peolpe can 'nominate' a "white liberal" to be replaced by a poc. Talk the talk, walk the walk ;-) walk out of your profession or position of power. The liberals will feel the heat themselves first and change their rethoric or will be replaced.
