I have no tolerance at all for Nazi sympathizers, courtesy of having known people who survived the camps.
I have no sympathy for Nazis either; I had relatives murdered by the Nazis in two occupied countries.
I would have loved to see your reaction at one of our local gun shows; There were two older German gents who were
actual Nazis and were proud of it. One was a little more vehement about it than the other. I believe they have both passed away since.
I learned that no amount of logic, facts or otherwise can change a zealot; They understand one thing, and that is violence.
