Mistakes happen. If we learn from them they become lessons.
I do see this in terms of idea and theory, as well as practice. These protests are a legitimate response to systematic abuse. It clearly has peoples attention, and that's a good thing from my perspective.
I don't want to be wrong, so could you clarify exactly how I'm wrong? In supporting protests? In taking the letter you cited on its word that social distancing and other preventative measures should be taken by protesters?
I can only guess that you are against these protests, in that you quoted them as "protests" and can only cite the the negatives you see (not enough social distancing and too much violence).
If the current administration prevails, I will indeed be on the wrong side of history by virtue of who is writing it, and why. I'm proud to be on the side that opposes fascism and I don't need external approval to know that authoritarianism does not promote a just society.
