Okay look I don't mean to sound harsh here but you folks are seriously going to have to get over SOME of this stuff, they are INITIALS this time totally unrelated to SS it's a coincidence that SD happened to also be a german "security" group.
All the good initials with SECURITY in it are already taken by SOMEBODY I can almost be sure of that so the German folks would have to get over looking up every set of initials going 'Where they someone evil?" or else nothing won't offend
someone out there. lol and I am not making up yet another security agency just because of one letter
Also do me a favor and translate what the SS and SD's names mean in English because unless it stands for Security Division or State Security then I don't think there should be any cause for offense.
