It makes me so sad that I think you are overestimating how much the average American cares if the election is stolen. Put another way: Tons of people, millions and millions, think that Biden stole the election, and no one started a civil war about it. The actual action was limited to the fringes of the fringes, and it didn't work.
Also consider this: BLM was one of the biggest protest movements in history, with about 20 million people participating in some way. But, it was only 20 million. Compared to the kinds of uprisings they had in Eastern Europe that actually overthrew the corrupt dictatorships, it was small.
Also, by coincidence, 20 million is almost exactly how many people went to the Gulag (out of a much smaller population.) You might say, "Well there's no way they could steal the election and then send anyone who complained to one of these detention centers they're desperately building right now at tremendous scale. There would be an outcry. People would care enough to stop it." Well, maybe. On the other hand, they're Gulag-ing thousands of immigrants currently and have now moved on to a few dozen citizens, and who is stopping them?
