"I find your lack of grammar disturbing."
Well, my first problem is why people like you find the Swastika funny to put as your emblem. The Nazi party was headed by Hitler, a dictator that caused World War 2, and resulted in 72 million deaths, including 6 million Jew deaths. I don't know about you, but I wouldn't find that funny, considering that all those people killed were someone's brother, sister, husband, wife, son, or daughter that would never see their family again. I'm going to assume that you are under 18 and not German, so I don't see why you would want to affiliate with that politcal party in any way, shape, or form. That would be like me putting a picture of two planes crashing into the twin towers and putting the infamous "HA HA" emblem piece on it. That wouldn't be funny at all.
And secondly, an emblem is something you should create to represent you. I like the band Bon Jovi, so my emblem is a copy of one of their album covers. It represents me, and it doesn't offend anyone on a high scale like that (unless people take offense to a spinoff of the Kool-Aid man.)
As for the Nazi Zombies, the only video game of Treyarch's that I'm familiar with that has the zombies labeled as Nazi are from World at War. And if you're going to find it wrong that they made the zombies Nazis, I really don't want to have to be the one to point out that THE FIRST FEW GAMES OF CALL OF DUTY WERE MADE WITH GERMANY AS THE ENEMY.
In all, you deserve it. I'm tired of seeing emblems of penises and emblems that these people think are funny, when they're just plain out obnoxious. Maybe they may let you use it again when you mature and grow up.
