None of this is entirely new. Americans have always fetishised their constitution or founding fathers. While there has been an era of free trade, that is over, and I think the west in general is in a difficult position (ultimately as a result of believing the "end of history" BS).

As for getting shot, while the chance of getting shot in the US for opposing the government is much higher than in similar circumstances in somewhere like the UK (which is far from perfect - but rarely actually shoots people), its also much, much lower than in Iran or China or Saudi Arabia.

Pushing back against the US government is a lot safer than taking part in something like the 2022 protests that ousted the Sri Lankan government, and lots of normally apolitical people took part in that (which was why it succeeded).
