I've talked about this in smaller contexts, but I haven't found any traction and time is getting short. When the Nazis passed the enabling laws for the book burning on April 8th, 1933 — exactly 90 years ago in 34 days — the first thing they burnt, the same day, were the archives of the largest trans and gay research institute in the world. When they say now that we didn't exist until after the war, the only reason they can get away with it is that they burned all the accumulated evidence.
