Yes, things tend to calm down. If you read history books about US history, there were times in the 1800s where brothers were killing each other over slavery and where people were killing themselves in the 1950s over their children's sexuality. Time heals wounds, and people tend to swing in a pendulum from progressive to conservative and back again (the 50s, the 90s, the 10s).

I recommend The Lavender Scare by David K. Johnson. It's a fascinating book back when the US government shared a frightening similarity to the CCP. It shows how a community develops in the postwar period, how a moral panic gets set off, how people are affected, and how a social movement starts and heals the country over time. It is almost a word for word copy of what is happening in the US right now, and how people in the past defused a situation that was even more loaded in some ways than today's world. If you are looking for reassurance, it's a great read. Many of the landmarks in the book are still standing, by the way :)
