Profoundly wrong statement.
First because that's not how Marxist-Leninists use the word 'liberal', that's a definition you just made up while ignoring decades of literature. Second, because it implies that is not what the word actually means to literally everyone, not just Leninists or even just socialists, everywhere on the planet with the exception of the US liberal duopoly.
Third, because it mistakenly assumes people are calling you a liberal because of your instance, and not because of your shit takes.
