I've lived in several countries for over extended periods and still follow the news of all of them and maintain contact with people there. While that may not qualify me to know all the intricacies - I will still double down on the idea that the US is far more extreme in almost all categories. The whole notion that there is only a right or wrong with people hung up on left or right, conservative or progressive - is taken very very far. Just the sheer volume of media outlets catering to every niche alone doesn't compare to anywhere else. The whole idea that you shouldn't talk about politics and religion in America holds some truth. Unless you're speaking with a kindred spirit, any sense of measure is often quickly lost. It's the story of one of us, or you're against us - and the trenches being dug are deep.
