So's Paul Stanley (or Stanley Eisen to his mum). In fact, Gene Simmons' mum is a concentration camp survivor, so you can imagine when some of the bands detractors in the US were calling them Nazis in the 70's( how they worked that out I don't know!), it was more than just a tad ironic to say the least.
Mind you, apparently the Christian right thought that the name stood for Knights In Satan's Service. Mad.
