Do American Neo-Nazis care about German culture and the German language, or not really?

Yes that’s the usual excuse. Funny how it often seems to be just one side.

Well I never been to Deutschland
But I kinda like the bratwurst

As I noted above, any growth in that industry now is pure fanboyz & modern racist skinheads, not amateur historians.

For all the discussions & reading since I was a kid about folks who own or collect Nazi memorabilia, I don’t think I have ever even heard of anyone collecting the contemporary Italian Fascist memorabilia. Not the weapons, not the clothing, not the symbols. Odd that.
