Neo-Nazi is the name given to Nazis who continue to practice the political ideology after its political elimination following World War Two. More than 40 million people were killed in the European theatre of Second World War, initiated by Nazi Germany. Neo-Nazis promote "psuedo-scientific Racism" which they use to discriminate against ethnic minorities. Neo-Nazism is a political ideology which has its roots in Nazism promoted by Adolf Hitler. Today it involves such ideas as Holocaust denial.
The most popular Neo-Nazi site is Stormfront, which has a large membership of Trolls and also Slavic people. This is notable because Hitler regarded Slavs as subhuman and wanted to exterminate them.
In addition, most Neo-Nazis in America would fail Nazi Germany's racial tests for higher jobs because the majority of Americans have recent genetic admixture with African Americans and Jews. Neo-Nazis are, incredibly, even worse and more unreasonable than die-hard creationists.
