You have already received good advice around this. I just need to add how sick I am of this appropriation of the Holocaust. It is so maddeningly ignorant and distasteful. There should be a permanent moratorium on such rhetoric. Even casually calling someone "Nazi" creates what is called semantic bleaching, whereby words lose their meaning and force through continual misuse. Not so bad when it's just "awesome". But sorry, someone you disagree with is not a "Nazi."

Maybe we should start thinking of it as "the other N-word" to underline its harmfulness and unacceptability?
