Liberalism is a conservative ideology.

Hardly, you can't swap them out at all. Here's the key difference: Liberals and leftists often protest out of concern for other people: Police oppress Black people. The rich oppress the poor. Men oppress women. Straight people oppress gay people. That sort of thing. Even rich, white, straight, liberal men may share these concerns. Conservatives protest out of concern for only themselves: Black people oppress me. The government oppresses me. The media oppresses me. Immigrants oppress me. Democrats oppress me. Feminists oppress me. LGBTQ people oppress me. Atheists oppress me.

Big difference there.

Just because they don't fuck with politics, doesn't mean politics won't fuck with them.
