I lived in Russia, New Zealand, Canada, and US. Of the four, US undoubtedly is the best at protecting controversial political speech, which to me feels like exactly what you want to prioritize if you want to maintain a free society.

I feel focus on the first amendment gives people of this bent cover: it lets them exert incredible power over speech in every practical way, while claiming that free speech is intact because there's no violation of the constitution. The fact that we need to clearly rebut people like this is exactly one of the reasons why I feel over-indexing on the constitution is unhelpful.
I'll leave the question of "should a person be branded for life even if they've done everything they can to make things right" for the reader.
