In many ways the effectiveness of the German war machine during WWII has been overblown and fetishized over the years even among people who don't approve of the Nazis. On one hand I don't mean to imply that that German war machine was ineffective. But part of the reason for their early success was because they were the only ones prepared for war. They caught most of Europe and the Soviet Union with their pants down. I don't mind playing the Germans, the Confederates, or any other evil empire in whatever wargame I'm playing. But I sure as hell would never cosplay as a member of that group nor would I tout their superiority. They lost after all.
He's one of those guys I hold up as an example of something from real life that sound completely implausible. If I was running a game in the 1960s and someone came to me with that backstory I'd think, "This is unrealistic and stupid. Change his backstory." But, no, real life is once again stranger than fiction.
Of course I am from the other side, my Mother's family were practically wiped out by the Germans, not only Czechs and Jews, my sister doing research on our village, has found some of our name were Sinti, Gypsies as westerners call them. The Germans didn't even consider what they did to them a genocide, murdering them at Auschwitz, until the 1980's.
Soviets were properly terrified, outnumbered 2 to 1, vs an enemy that they had lost WW1 to, and the "Workers' and Peasants' Red Army" little better than a poorly equipped revolutionary militia. The Germans were in their time the most powerful army; it was their racism of the Nazis that killed them. We would not had the breathing room to reorganize, move our industry, had they not had the weird duplicity of what they were doing. Still I see people back at home sometimes lionize them, and its like, uh, they murdered 27 million of us?
Playing war games, the Germans are the most gameable side, I don't necessarily look down on people for playing that side. Sometimes I question game designers concepts, such as Red Army troops in Squad Leader having a range of 4 and Germans a range of 6, when the average Soviet was far more likely to have used or own a rifle.
Nevertheless, having neo-nazis hanging around your business is very bad for business, beyond just their vile beliefs. They will drive off any normal customers.
