Nationwide Membership: 5,000

Explain to me what 5,000 KKK members has to do with your claim that there are 12 Nazis.

Only write me a letter, because you're banned.

Nationwide Membership: 5,000

This is also a false quotation, bronto.

The article says: 5,000–8,000.

The alt-right, or alternative right, is a loosely-connected and somewhat ill-defined[1] grouping of white supremacists/white nationalists, neo-Nazis, neo-fascists, neo-Confederates, Holocaust deniers, and other far-right[2][3][4] fringe hate groups.

The alt-right movement has been considered by some political researchers a terrorist movement and the process of alt-right radicalization has been compared to Islamic terrorism by political scientists and leaders.[190][191][192][193][194]

A research study of 447 self-identified alt-right members found higher levels of psychopathy, narcissism and Machiavellianism compared to the general population; and that members of the alt-right were more likely to express prejudice against black people and admit to engaging in aggressive behavior. Alt-right members also had significantly high levels of dehumanization, with the mean alt-right scores comparable to how the general public views the Islamic State of Iraq and the Levant. Alt-right members viewed Hillary Clinton, Muslims, feminists, Nigerians and journalists as the least well rated groups on the dehumanization scale while white people, men and Americans were rated the best.

A paper on the subject stated that it clearly fell under an extremist movement, saying that "alt-right adherents also expressed hostility that could be considered extremist: they were quite willing to blatantly dehumanize both religious/national outgroups and political opposition groups"
