People are really making a mountain out of a mole-hill on this one. So what if one guy was offended and asked for a refund. It's fully within his rights to do so. Good on him for standing up for what he believes in.
It's because he was more than likely being opportunistic and used a very illogical reason to get a refund. I wouldn't be surprised if he wasn't offended by the game in the slightest.
