I'd hate to see how you react to real problems in the world.
Just like how this isn't a real problem either?
User driven content should never be censored; while reasonable or not, you're putting limitations on the people that are basically enhancing your own product. At the very least, there should be filters for maps or perhaps labels denoting that maps may offend users. This is just blizzard taking the lazy way out.
UMS maps were a big reason why I got sc2 in the first place; I would've questioned my purchase had I known that all these limitations were being done. That's what I get assuming the same quality for sc1 and wc3 would be passed on to the 'improved' battlenet.
If the reason for the banned map wasn't such a ridiculously weak argument, I wouldn't care as much. Why not use some common sense rather than being so deathly afraid of the remotest offense? I could also weakly argue that textures of a random map offend my individually created religion. Not doing anything would be discrimination.
If there's any resemblance of N4zis going on, it's not the map or mapmaker.
