We have people in power who explicitly want to exterminate minorities (see those leaked text messages) and we have a sizeable population willing to trust and empower those people. It's not bending the definition to call them Nazis.

They didn't build Auschwitz the day after Hitler got appointed chancellor. They built up to it. I don't know how you can look at a government that's literally building and populating concentration camps with people who haven't broken the law and clutch pearls about calling them Nazis until they scale up sufficiently. The best thing you can honestly call them is proto-nazis.
