And why does it have to be stopped exactly? Or did I misread and that’s sarcasm?
You really need to ask? Leftist discourse is inherently anti-authoritarian. When people form communities and start acting in their own best interest, they begin working against the interests of capitalist slavers.
Liberal discourse is inherently antiauthoritarian. Leftist discourse, including progressive and far-left rhetoric, is inherently authoritarian.
Bless your heart. Liberalism is right wing. Leftist discourse is anti-hierarchy. You’ve been fooled into thinking China and Russia have tried leftism. In each case, a hierarchy of power determined distribution of wealth, privilige, and freedom. Leftism is community building, direct action, egalitarianism, anti-hierarchy and anti-authority.
Liberal discourse is at most anti-regulation, but it’s fully supportive of wealthy powerful people being as oppressive as they may feel like. It calls it “freedom” when corporations submit people to their demands, by glossing over power disparities.
