What I read about the current climate in the US reminds me a lot of how things were in the months after 9/11. While I don't have unbiased data like in the link, I can share a personal anecdote: In the months after 9/11, if you spoke up and said you didn't agree with US foreign policy (invading Afghanistan) or that you didn't approve of Bush and wanted him to resign, you got blacklisted. I had a friend, every house in his neighborhood had an American flag except for his, because his dad was an introverted engineer and uninterested in politics. The absence of the flag was obvious, and after a few nights of things like eggs on the door, flaming dog shit, and finally a dead animal left on the door mat, he put up an American flag and all the drama went away.
