The following civilizations would like to have a word with you (that I know off the top of my head): Chinese, Japanese, Ancient Egyptian, Ancient Persian, The various Babylonian/Assyrian Empires, The Roman Republic/Empire, Ancient Greece, and more that would end up having a bunch of DLCs for any modern Civilization Games past Civ1.
There
is a distinction between the two groups. Other than leftist viewing liberals with disdain and animosity. Leftists want a complete abolishment of the economic system of capitalism and replacing it with another economic system. Either through gradual reforms or, in the case with far-left politics, through a violent overthrow through a revolution and accelerationism.
Hell, Leftists aren’t amicable towards Social Democrats and don't
consider them "leftist" (Yet SocDems do hover around the center-left quadrant the last I checked on the Political Compass and the Wikipedia article I've looked up in) because SocDems want to reform and humanize capitalism and take a gradualist, reformist, and democratic approach to achieving socialism. Tankies
ESPECIALLY loathe SocDems because they reject wholesale the idea of a violent revolution, authoritarianism, and accelerationism and Tankies themselves
hate the idea of a representative and participatory democracy (Not to mention haven't gotten over the whole kerfuffle in Germany in the 1920s).
As frustrating as it is that I’m considered a “right-wing chud Gamergater Trump QAnon cultist” around these parts, I do know the difference between Liberals and Leftists. The attitude of "make little distinction between leftists and liberals" is no different than the attitude of the terminally online leftist on Twitter/X/Reddit that conflates your average milquetoast center-right conservative with Nazism and Fascism.
