‘Liberal’ is one of those words that has so many definitions that it can have contradictory meanings. It can mean ‘open to / tolerant of’. It can denote a style of education that tries to be broad rather than deep. It can describe various political positions - the ‘Liberal Party’ is left-wing in Chile, centrist in the UK and Canada, and right-wing in Russia, Japan and Australia. This is also what OP is memeing about. At this point, to avoid confusion, I would just avoid using the word except in the purely academic / technical sense.
