Wow. Tu quoque and whataboutism as proponents of various Big Truths claim the other stinks. On ISF. Truly, we have indeed become the empty ranting echo chamber we often bemoan in Community. Skepticism? Meh.
Speech that directly denies or seeks to suppress political equality does not deserve protection within the same political system that guarantees that political freedom, as it denies the very foundation of the freedom it claims to do so. Logical contradiction is not a valid foundation for law. It creates permanent conflict and undermines the legal system and democracy. Jim Crow, for starters. North Carolina. Babies in cages. The contradiction persists in the US because of the progressive enshrining of the Founding Fathers and Constitution in – vomit your guts out – "divinely inspired" or "übermensch" clothing. The GOP has publicly shoesized its democratic IQ in an attempt to make fascism sound like sunshine and flowers.
I hold to the exact same position wrt religious doctrine: those creeds that would deny freedom of religion to all other faiths cannot possibly deserve protection under that very same freedom, or it is no freedom at all. Currently, Christians are the worst offenders, but the other Abrahamics are close behind, taking turns with their threats.
The enemy of any single political freedom, or all such freedom, is totalitarian doctrine, be it religious or political. Historical inevitability, racial purity, nationalism, an Abrahamic/Hindu/Buddhist neck slicer... whatever: all crap. Perfect truths, on human faces, wear a death mask. They all deserve Hume's Guillotine.
