And yes, people did call him a nutcase. Maybe not by saying “You’re a nutcase, Xwing!” but in essence they told him he was full of it.
Hades, your attempts at revisionism are quite silly and immature. You claimed that Mazrim Taim was calling me a yokel; he replied, “Fool, don’t put words in my MOUTH!” You thought Cless’s compliment was a joke, so you replied, “He’s hillarious. lol :P.” He answered, “No, seriously.”
Furthermore, when I argue, I’m not looking for group popularity. It’d be easy to eloquently argue that dressing up as a nazi is evil, and condemn these Japanese cosplayers. That’s one shortcut to popularity, to always say what people want to hear. I also think it’s fairly despicable. So <i>even if</i> anyone besides you started exclaiming, “You’re a nutcase, Xwing!” I wouldn’t be concerned.
You, on the other hand, seem to think it’s very important to have the most popular opinion, to have everyone agreeing with you. Your post after our first argument read, “asserts victory because he’s cool like that.” You’re <i>still</i> desperate to convince everyone you “won” the argument, posting things like, “And yes, people did call him a nutcase. Maybe not by saying ‘You’re a nutcase, Xwing!’ but in essence they told him he was full of it.” If you want to assert “victory” further - whatever “victory” means in a message board argument - feel free. Then you can rest easy, having temporarily dealt with whatever insecurity is behind your immature posts - such as the following:
I just kinda decided to pre-empt his dillusions before he even started spitting them out because it’s so typical of people on RPG forums to do so, and that’s why I unconsciously went off on topics he didn’t even touch 
I went to dictionary.com, and looked up “inferiority complex”. It reads, “A persistent sense of inadequacy or a tendency to self-diminishment, sometimes resulting in excessive aggressiveness through overcompensation.” Indeed, excessive aggressiveness through overcompensation. Please, Hades, deal with your inferiority complex somewhere else.
Now, back to the argument. There have been dozens of posts since I last looked over this thread, so, rather than reply to them all, I’ll rephrase what I’ve been saying.
So, you think there’s something wrong with cosplaying a nazi. The first question to ask is, why? What makes it wrong? Then you go through the possible reasons: “Dressing up as something evil is wrong.” Okay, except that people dress up countless “evil” things, whether on Halloween or while cosplaying. Pirates, murderers, crusaders, etc.
Next possible reason for it to be wrong: “Dressing up as something offensive to other people is insensitive and cruel.” Sounds okay, except that people conveniently forget this as long as the costume in question isn’t a nazi costume. I know extremely religious people that are offended by witches on Halloween - yet you’d agree it’d be silly to worry about them being offended. So sensitivity clearly isn’t the issue.
Next possible reason: “It’s okay for people to be offended by some things (like nazi costumes), but not others (like murderer costumes).” This is where the idiosyncrasy becomes apparent. Why is it okay to dress up as a murderer, but not a nazi? An individual, nazi soldier <i>is</i> just a murderer. There must be some sort of taboo on the idea of “nazi,” because the way nazi costumes are treated is very inconsistent with the treatment of other “evil” costumes. But it is just taboo.
It’s very difficult to make people realize that their convictions about what’s “okay” and “not okay” are simply cultural taboos. It’s easy to mindlessly reaffirm those taboos - e.g., “It’s not just a costume, it’s fucking nazi get up.” Nevertheless, a taboo is a taboo. It’s not some <i>special</i> insight to the moral order of the universe. A costume <i>is</i> a costume, whether nazi or witch or murderer. There is no reason, consistent with the rest of our behavior, for condemning these Japanese for cosplaying as nazis.
