@floofloof@lemmy.ca has a better response to this than I can write

liberalism is a political ideology rather than a political party, and that the problems of liberalism extend beyond registered Democrats. It’s important globally too: liberalism is problematic everywhere, whereas the Democratic Party exists only in the USA. Whatever a politician’s party, if they subscribe to liberalism their politics are going to problematic in the ways liberalism always is.

From that Wikipedia link:

Liberalism is a political and moral philosophy based on the rights of the individual, liberty, consent of the governed, political equality, the right to private property, and equality before the law. Liberals espouse various and sometimes conflicting views depending on their understanding of these principles but generally support private property, market economies, individual rights (including civil rights and human rights), liberal democracy, secularism, rule of law, economic and political freedom, freedom of speech, freedom of the press, freedom of assembly, and freedom of religion. Liberalism is frequently cited as the dominant ideology of modern history.

Establishment Democrats are a problem that was created by liberalism, just because neoliberalism is dead as an ideology doesn’t mean that the structural impacts that have been established over decades of uncontested domination in the sphere of ideas by liberalism/neoliberalism aren’t still dominating the currents of power in the US and elsewhere.

Neoliberalism attempts to hallucinate some middle ground between the brutality of wealth inequality, colonialism and extractive capitalism and progressively better treatment of human beings on the other and there just isn’t. I don’t know what more evidence the world needs, the majority of people in the US have realized it, but the neoliberal wing of the ruling class in the US is still utterly in denial about it.
