They know exactly what it is.

They are two versions of illiberals: Those who mistakenly assert that Liberalism has no boundary condition, and thus must be applied to all aspects of reality (rather than as a political framework); or are National Socialists: who see Liberalism as an arch-enemy that rebukes their collectivization.

Those are the two positions. Anyone who says otherwise is a liar who is attempting to obfuscate that they are either a generic illiberal, or a NatSoc illiberal.
