It's playfully provocative, perhaps one could argue making any kind of game on any kind of topic is trivializing, their are many WW1 and even more WW2 games. Do you find the C&C red alert games offensive as you play as Stalin? I personally would say these things are perfectly allow able as is this game.

On an aside this is the first game in a while posted on Hacker New that looks well made and not a soulless sloppy mess.
