The only one uneducated about political ideologies is you. You're projecting.
Capitalism is the private ownership of the means of production. And also, socialism can operate under markets (ie. market socialism). And capitalism is hardly voluntary. A single mom forced to work three jobs to sustain her family is not voluntary. Someone taking a terrible job because of the health insurance is not voluntary. Work or starve is not voluntary.
If you seriously believe that there is no oppressor class in America, then you are really, really ignorant.
Conservatives despise big government when it helps individuals, and.......get this.......increase economic freedom. You loathe basic social programs that objectively help the poor, increase their happiness, and the length of life. However, they adore big government when it is actually wielded to decrease freedom, whether that be through the police, the military, they're love for censorship (their love for Joseph McCarthy immediately comes to mind), etc.
I'm no history expert, but I guarantee you your explanation about "marxism" is utter BS. Marxism for starters is not an ideology, but rather a critique of capitalism and feudalism. Socialism is the ideology which replaces capitalism. The democrat party of old was extremely racist, which is antithetical to the tenets of socialism, which advocates for equality. The farthest left democrat I can think of in the early 1900's is FDR, and even then he's not a socialist, he just advocated for welfare policies, which worked. Additionally, the modern democrats as whole are in no capacity "marxist". 99% of them are liberals and 1% are social democrats (Bernie Sanders, AOC, etc). And since when were any republicans marxists lmaoooooooo. You claim that you don't call anything you don't like marxism, and then unironically call some members of the republican party marxist. That alone is an indication of your political illiteracy. What, Mitt Romney thinks black people shouldn't be killed by the police? Marxist I say. John McCain doesn't want millions to lose their health insurance? What a commie! Lisa Murkowski and Susan Collins want to follow precedent set by the Republicans in 2016? Must be a big guberment leftist who hates freedom.
Please, please, please, I beg of you to learn the differences between political ideologies, because you're literally lumping fascism, socialism, marxism, liberalism, and conservatism all under the same ideology and it's really embarrassing.
