Fascist is a social slur for rich people who don't care about poor people. Antisemitism is the term for Jew haters, xenophobics extend this to culture. There's no such thing as neonazis. Those who draw swastikas (symbol of Buddha) and preach Hitler BS are mere racist criminals who end up in jail. They may as well be labelled cunts.
Wikipedia quotes a book on it with this definition:
Neo-Nazism consists of post-World War II militant social or political movements seeking to revive and implement the ideology of Nazism. Neo-Nazis seek to employ their ideology to promote hatred and attack minorities, or in some cases to create a fascist political state.And the Southern Poverty Law Centre says:
Neo-Nazi groups share a hatred for Jews and a love for Adolf Hitler and Nazi Germany. While they also hate other minorities, gays and lesbians and even sometimes Christians, they perceive "the Jew" as their cardinal enemy.I'm glad to see my basic understanding was actually correct. Veritas, language evolves and words have meaning. This^^ is what Neo-Nazi refers to. I'm frankly at a loss to understand why you find this objectionable or insist it's not a real phenomenon and the term a real name for it.
None of the things you describe: racism, antisemitism, xenophobia etc adequately describe this species of animal we call Neo-Nazism! It is not just a negative attitude towards a group, it is a political ideology, a supremely fascist one, which follows Hitler's so-called 'philosophy', world-view, policy or at least is working to effect them should they gain power. The term Neo-Nazi fits, is adequate and correct.
Yes, the Nazi Party of Hitler's era does not exist, but that's why no one calls them 'Nazis' but rather Neo-Nazis. Again, I'm confused what the issue is here to be honest. What is problematic about identifying people who embrace Nazi beliefs and ideology and even policy (intending to effect them should they gain power) by the term Nazi but adding Neo to differentiate them from the members of Hitler's party? That seems to me like denying there's a group of people who are fundamentally about actual Nazism. And no, they're not all in jail. Most are not, in fact! Look at that long list of Neo-Nazi groups in that SLRC report:
