I think my main level of discomfort was not so much the subject matter (although...) as the suggestion that the current Germans are "guilty" A bit like I don't really have a problem with saying this virus originated in China, but I do have a problem with people in America attacking anyone who "Looks Chinese" in the street. It's not my fault they're so stupid, but I'm ok with not calling it the Chinese virus in a place where these dicks might latch on to that if it helps protect innocent members of society.
I just feel children should not be responsible for the sins of their parents... I'll shut up now...
