In a very reductive sense it means if you’re offended by being called it, then it means you.

Wannabe pejoratives usually are overly reductive.

I just think the tankies and MAGA types don’t even know what it really means. Republicanism and Marxism are historically both liberal political philosophies that find their roots in the enlightenment.

I think they want to say “corporatist neoliberal”, but it’s too many syllables or requires too much thought. “Lib” makes for a nicer stone to throw.
