Anyone who disagrees with you on anything. The word has lost all meaning to
people just throwing it out at random
people on reddit,
tumblr, and twitter. It no longer means you believe in the word of Nazism, but more you don't believe in things like dreamgender, other opinions, or otherwise.
Person
1:
Hey did you hear about Popular person on twitter?
Person 2: Yeah that Nazi decided to post some less than ideal shit.
Person
1: Nazi's killed millions, they weren't called that because they didn't agree with someone online.
