in most of the world, “leftist” implies that you are anti-capitalist, while “liberal” implies that you support capitalism. Leftists believe workers should control production, while liberals believe owners should control production. Liberals might be “left wing on cultural issues” but it’s a lot less consistent among liberals than among leftists. You can find, for example, a large number of anti-trans liberals, but you’ll have a harder time finding anti-trans leftists.
