Political Memes

There's lots of discussion below, but liberalism is the belief that enfranchisement and liberation comes from private property, which at one time was progressive in the face of feudalism. But since WW1, liberalism has not been a progressive movement as it has captured all of the private property in the world. Liberals are capitalists, leftists are not. Leftists (mostly) believe in class struggle, liberals (mostly) do not.

Leftists see the problems with private property and strive for social enfranchisement, even at the expense of private property rights, particularly where such "rights" are a function of one dominant class over the rest. To leftists, the social is material. Liberals mostly struggle to even conceive of this.

There are not clear bright lines, it is a messy spectrum of belief and politics, particularly in the US where we are so individualistic. For example I usually find it easier to work with so called progressive liberals than authoritarian leftists, although this can vary dramatically over a variety of political issues. Sometimes Authoritarian Leftists work best with Progressive liberals, and leave moderate, practical leftists out! So there is no simple formula, except to deal with the actual conditions and act on behalf of the whole working class, rather than a particular group or unique subset of interests, in the struggle against the ruling capitalist class. This looks different in different places to different people, progress and truth is borne out of actual class struggle.
