Seriously! There's a ton of stuff on YouTube. I searched for and bookmarked a couple of Wagner pieces, and I have to minimize the screen when I play them, because the Related Videos display is full of Nazi references, and German ultra-nationalist posts, showing either Nazi version or pre-Nazi version of the Reichsbanner. A lot of people out there have a fascination with the period, many probably an unhealthy one.
Could be worse, could be like those knuckleheads over in Phillipsburg that named their kid Adolf Hitler. Then they got mad when the grocery store wouldn't put that on a cake they ordered. I mean, they can name their kids what they want, but please don't be surprised if some people find it offensive.
