The Republicans have been playing by the nazi playbook for a long time now.
Nazis didn't start with the Jews. They knew they couldn't get away with rounding up an entire ethnic group. They started with the LGBTQ community. They dehumanized lgbtq people in the eyes of the public and made it seem like they were doing it for the good of a pure and powerful Germany. When that worked they realized how easy it was to dehumanize an entire population in the eyes of the public and used the same tactics against Jews, Roma etc.
When you think about it the lgbtq community is the first line of defence protecting democracy because they are the most vulnerable and easiest to demonize. Once it's ok to eradicate one group of people it becomes so much easier to do the same to larger groups.
It won't stop at lgbtq people, they will keep eradicating every minority until they're actually stopped by force. So far they've gone after trans people, gay marriage, women's reproductive rights and have even talked about overturning Loving vs Virginia. Their goal is a straight, white, "Christian" male utopia.
