I had a big long babbling post to set the record straight. But... meh... So I'll keep this short.
Yes, I've been to gun shows where there was Nazi paraphenalia. Gunnies are history and WWII geeks. So a table with a WWII German uniform would be expected
But they are few. It's not at all like the Leftist Paranoids want it to be. 'Hotbeds of neo-nazi recruiting! Wooooooooooooooooooooooooo... '
Sure, I've only been to a handful of gun shows. Maybe Nazis are more prevalent outside of suburban northern Virginia shows. Reports from gunnies in other regions seem to jibe with my experience.
So why are we tarred so much by these Nazis? It only takes one to make a serious impression on the naive, and to give plenty of ammo to Lefty propagandist, willfully ignnernt. That and Lefty wish fulfillment.
