Some of the very first people that the Brownshirts went after was transpeople, even completely destroying an institute that was studying gender in the 30’s.
It's not like the people involved in that lynching felt bad about it or regretted it. And then they passed that hate to their children who passed it on to their own children. Those people were the grandparents and great-grandparents of these kids. Some of them are still alive and still preaching their hate to the kid. Some of them were alive long enough to do it before they died.
