I think you're using the common US political definition of "liberal" (which is close to a synonym for "progressive" or often even just "Democrat"), whereas at least to the point of your grandparent comment, my interpretation is that the definition being used is more like "classical liberalism"[0]. I'm not trying to be pedantic, but this is a common and unfortunate confusion that makes these conversations extremely muddy.
