Communists are being pretty explicitly anti-liberal, and they make that a point pretty often.

And is becomes clear eventually as you see their posts and read their comments that these people aren’t misunderstanding liberals, they’re pretty aware that both in the meaning of the word and in practice, “liberals” generally want people to be free from shackles and free to do most anything. Typically summarized along the lines of “as long as it doesn’t hurt anyone, do what you want”.

Communists don’t agree with liberalism.

Communists want to demand much more of people and permit much less. They have much more in common with Putin’s extant but inflated voterbase than they like to admit. Even with Putin not being a communist.
