“What kind of people was I visiting?”
I would say that you were visiting [and were returning home to] normal ordinary people and majority of them would be equally appalled by your encounter.
Unfortunately Nazi still exist in the wild and they are more frequent than they should be. They should be extinct like a Dodo but there are still some “people” who “think” (I don’t think that they have a mental capacity to think, really) that they are [born] better/more deserving… than other people.
This is the notation that gave birth to all genocides in human history.
