We have these imbecile skinhead brats in our country, too. They are idiots with their brains (if they had some brains in their life at all) blown away by nazi propaganda ... eh, it's a civilized society here so that I won't continue. But be sure that if I detected even the smallest link between MM7 and these idiots then I'd never run the game.IMO, it's a coincidence. Among others, the game is too sophisticated to be created or played by these idiots. Compare MM7 with nazi stupidities, which you can find on the web and see which kind of games is liked by these idiots. Also note that the game does not contain any racist ideology so that it must be "wrong" for the idiots. Thus, the link is highly unprobable.
The name "Blood and Honor" is much likely a general slogan of a party which you play in the game than the nazi propaganda slogan. The creators of the game did not check, which slogans have already been abused by nazis. IMO, that's all.
