They did have songs called ‘Blitzkrieg Bop’ and ‘Today Your Love, Tomorrow The World’ (lyrics: I’m a shock trooper in a stupor yes I am/I’m a Nazi schatze you know I fight for the fatherland), though. I don’t think they did it for shock value as much as to represent mindlessness.
Also, the Dictators, who were probably somewhat of an influence on Kiss, were all (more or less) Jewish, and they also took the mickey out of the whole thing with ‘Master Race Rock’ and Next Big Thing (We knocked 'em dead in Dallas, We didn’t pay our dues, We knocked 'em dead in Dallas, They didn’t know we were Jews)
