Actually it's been something of a hot issue with the mod staff for some time. Recent (and by recent, I mean more than a month ago when I made the rule, closed your thread and posted the rule in your thread) threads just brought it back up and finally broke the fuhrer's back, so to speak.
Every time someone talks about the nazis it turns into a flame war, because 99% of the time, it's some twit trying to get attention. If you're not a twit trying to get attention, then I'm sorry, but they already ruined it for you. Actually, Hitler already ruined it for you, but that's neither here nor there.
This wasn't aimed at anyone in specific...trust me, we don't need to make up new rules just to target someone specific. That'd be both unfair and a huge waste of time, since if we're out to single someone out we'd just ban them and laugh about it. Making up rules to justify it just makes us look weak, instead of distant and terrifying
If you want to continue posting your models in the gallery, that's fine (Unless we start getting complaints, which we haven't yet), we just don't want it spilling over into the forums. If that means you can't post nazi related fluff about your army, or ask which colors work best with a swastika motif, then I'm afraid that's just the way it is.
The only way to head off a flame war about whether or not it's ok to invoke the Nazis is to simply not invoke the Nazis.
