The left has been winning in the culture war for many decades because it turned its political projection into a fool-proof methodology. The left’s method comes from philosopher/sociologist Herbert Marcuse. The left's method is why the left has come to control most institutional power in the United States (from corporate media, to academia, to the permanent unelected government). And until the right adopts the same method, it has no hope. However, if the right does adopt the same method the result will be civil war—unless the left calls a truce to stop using the method. But constant war is the name of the game of statism regardless. Voluntarism is the only viable way to defeat the left because it also defeats the right and so defeats statism. But that would require guilt projecting statists to give up statism in large numbers.
And I'll leave you with this amusing meme that illustrates the fate of the political right if the right doesn’t adopt the left’s "repressive tolerance" method for itself.
