I'm for it, I don't really give a rats about nazis one way or the other, but I'm a firm believer in the right of expression in any form. There's good, bad and indifferent world wide, facts and factoids...everyone perceives right and wrong in different ways. It's actually very bias not to allow it yet allow systems that others would consider equally as offensive...for example capitalism viewed by commies or what have ye.
Good or bad...right or wrong it's not for us to pass judgement on it. There are features that allow us to block players anyway so if ya don't like it then you don't have to deal with it.
