is there anything specifically Nazi about this besides that his name is German sounding
I hear "Luger" and I think of the handgun heavily associated with nazis that wehraboos cream themselves over
Another one that sounds really Nazi is Heinrich. Except that Karl Heinrich Marx died over 30 years before Heinrich Himmler was even born. This is just a case of everything German automatically sounding Nazi. Which, like, safe bet in general, but it's a disservice to automatically associate anything German with Nazis
You'll notice that the names I associated with nazis were Speer and Luger, not Marx or Heinrich
