I don’t encounter Nazis or white supremacists often. I do, however, encounter people who echo them and have overlapping “interests”.
The modern white supremacy movement lead by people like Richard Spencer and Jared Taylor is effectively a soft-core form of Nazism. It is particularly dangerous because rather than being repulsive to most people it seems almost reasonable and agreeable. If we have a black history month, why not “white history month” too, right? If Jews can build themselves a state why not whites?
They don’t need to call themselves Nazis to have an ideology that appeals to a ton of people. That is how one ends up having family members and friends who appear to be sympathetic to the Nazi cause.
