In addition to Cowbee’s comment, the Prolewiki article on Socialism expands on it.

• Socialism for Beginners

• How Capitalism Robs The Developing World

• What Exactly is Liberalism? (no, it’s not about being “woke”)

• “Yeah Capitalism Is Bad… But What Can We Do?”

“Human nature” is formed by societal norms, which are in turn formed by the present mode of production and thus material reality. Humans aren’t racist by nature lmfao, such a dumb right wing assertion.

• “But What About Human Nature?” is the Dumbest Conservative Argument

Simply put, materialism — as opposed to idealism — is the idea that everything we do and experience as a society (our history, culture, politics, etc) is shaped by the material reality around us, rather than ideas.

“Material analysis” in this case therefore means analysing politics and history through this lens. And it’s a fundamental component of socialism/marxism.

Yogthos is insulting liberals because liberalism is an idealist ideology that always eventually gives way to fascism when a capitalist state is (inevitably) in decay.
