I’m not talking about classical liberalism (which has no coherent clear application out of the context of the time and conditions around the mid-18th to early 19th Century; there's an infinite number of mutually incompatible applications of it to other contexts, including most of the modern American political spectrum.)

I’m talking about liberal and progressive as modern American political factions (which in major partisan terms, though the factions aren't tightly bound to a major party, map roughly to the right and left wings of the Democratic Party.)
