It used to be the case you had to do some pretty evil shit to be accused of being a Nazi.. These days though the word is bounded about without any real thought. That and "White supremacist".
It has gotten to the point now when ever I hear someone being accused of being a nazi etc, I just assume it is untrue. What this is doing is lessening the ACTUAL evil shit the Nazis did. If someone says anything that is in disagreement with someone about racism etc, it is so normal for someone to accuse the other as being a white supremacist.
In my mind this has devalued the words, making actual nazis seem like they are not that bad, and the same with white supremacists. I really wish that the undeserved accusation of bigotry was seen as being as bad as the accusation it's self implies.
