Of course we’re not Russia or Germany. I don’t expect mass arrests or killing on a mass scale.
What I expect is the loss of careers in academia, media, and government by those who don’t believe the prevailing ideology; harassment through regulation against groups and individuals who don’t try to get along; intimidation and threats, usually spoken in soft, kindly voices, with a smiling police official or a government agent standing silently in the background; silencing voices using laws against “hate speech” and “sexual harassment”; and, occasionally, a show trial for those few who are prominent enough or sufficiently vocal to upset the apple cart. I can see the apologetics even now: “He just lost his job, can’t he move on?” or “No one has the right to say things which can be interpreted as hate.”
The end result will probably be something on the order of the Glorious Revolution of the 1660s in England, with elites battling elites, institutions battling institutions, and a few prominent heads rollings, perhaps literally among the fanatics in leftist communities.
At the end, hopefully, we will regain our sense of freedom and individualism, in the same way that the English dealt with their issues of royalty, church, and rule of law. I have faith in the United States, and I really don’t see us at the end of our time in this world. On the other hand, for the next several years, it might seem that way.
I believe there’s truth in what you say and also that this will get worse before it gets better but I do believe we’ll overcome.
