Point is, it appears to be solely the US that holds its constitution in divine reverence as having already achieved perfection. (Only slightly tongue in cheek here)

Other nations have been more free amending their constitutions. Nations without written constitutions often consider that a feature not a bug. These can bend things out of shape differently. :)

It is perfectly possible to speak against the government, any government, without being racist, or inciting hate. It is not possible to speak against a government if you can't ridicule or caricature the head of state, or party a. Thus you can have free speech without also giving unlimited licence to be an offensive, racist jerk without consequence.
