It's just plain prejudice without facts. Just because they used slave labour in the war doesn't mean they do it now. In fact, it'd be a ridiculous claim. So picking on them makes no sense. It's rather the case that we all use slave labour. We can't even avoid it. Since you don't seem to know the difference between Krupp and Krups means you can't even be bothered to google the name. You would have a case with Krupp as they do make money with weapons, but that is not really unusual for such a company, is it? If you don't like Germans that's fair enough, you don't need to like them. But do you really want to hold a grudge against the grandchildren of the war generation?
