This sounds like a reprisal of the common far right bigoted refrain to platform "both sides" when we all know that reality obviously has a liberal bias [0]. This dog whistle for free speech was also used by John Stuart Mill, an influential figure in classical liberalism, the movement that provided the ideological roots of the modern alt-right extremist movement, in his treatise On Liberty from 1859 [1]:

wrong, it is thought, in restraining bad men, and prohibiting what
only such men would wish to practise.
