ignore the faggots.
If you are going to an animecon it's fine. It's the next best thing to cosplay.
I have seen some fucking lame shirts at animecons that this would be better then. (try half a dozen fat d&d nerds hitting on ugly ugly goth chicks while wearing a shirt that says "if your a goth, where were you when we sacked Rome?"
Seriously dont listen to the haters just dont wear it outside of conventions. And as a European you get a LOT more leeway on stuff like that. Americans wouldn't be caught dead listening to Falco and Hasslehoff.
