Personally, I wouldn't bother engaging with tiresome little trolls who smuggle their racist right-wing crap under the guise of mere "eccentricity". Plenty of them cruising the net, and they're all pretty transparent. Some of them might even have a peripheral interest in film music....
As I get older, I'm less inclined to debate with such specimens. Rather, I cheer the solution arrived at by my grandfather and some of his friends when the Blackshirts tried to march the streets of Newcastle in the 1930s - namely, they pulled the bastards off those streets and gave them a fucking good hiding. If a bit more of that kind of thing had happened in Germany.... well, you get the idea.
They say you mellow with age. Doesn't seem to be happening with me.
