I don’t know how you’ve been on Lemmy for two years and are hearing this for the first time. Previously:

Liberalism has a definition, which Marxists (and still many liberal Europeans) have never forgotten, though thanks to red scare purges and two cold wars, others have. Now, in Orwellian fashion, “liberalism” and “socialism” are floating signifiers, so we have liberals like Sanders calling themselves socialists, despite never calling for abolishing private ownership of the means of production.

Wikipedia: socialism: Socialism is an economic and political philosophy encompassing diverse economic and social systems characterised by social ownership of the means of production, as opposed to private ownership.

Wikipedia: liberalism: Liberalism is a political and moral philosophy based on the rights of the individual, liberty, consent of the governed, political equality, right to private property and equality before the law.

“Private property,” a.k.a. “the means of production.”

What people in the US usually call “conservative” and what they call “liberal” are both liberal. Fascists in the Republican party aside, both it and the Democratic party are liberal parties. And liberalism and fascism have more in common than most people realize.
