No it isn't.
Do you believe Jews, homosexuals and non-white races are inferior to straight whites? Do you believe the white race is the sole creator and rightful inheritor of civilization, and that multiculturalism and race mixing is a threat to that civilization? Do you identify as a Nazi, Neo-Nazi, white supremacist or white separatist? Do you believe the Holocaust either never happened or else that the Jews had it coming?
Then you're a Nazi.
Do you believe any of the above while supporting the use of violence to further those ends?
Then you're definitely a Nazi.
Do you identify as "alt-right?"
Then you may not be a Nazi, but you seem comfortable having them as allies, which isn't much better.
Do you use Nazi imagery and rhetoric ironically?
Then you're an idiot who wants to be mistaken for a Nazi as a laugh, so enjoy being mistaken for a Nazi. No one is laughing, though.
