In the mid aughts, as the US political train switched into overdrive towards fascism and autocracy (yes, the signs were evident even then) I did some deep dives on the holocaust, not just to acknowledge how bad it was (I did regret that) but also to understand the steps from just collect the undesirables and send them away to time to stuff the untermenschen into the giant execution machine and watch it go brrrrr
That way, when someone claimed it was inappropriate to compare what's happening in the US to the Holocaust, I could point out along the timeline where we recently were, and are now, and how the train is totally on schedule and we totally bought a ticket to ride.
It's not an eternal string of words, but it is a very grisly, ugly one.
