In attempting to infiltrate extreme groups, Patrik Hermansson's back-story was that he was an exchange student, studying in London: "I wanted to appear academic, because I knew they were interested in having people that were academically minded." His Swedish background also helped. Among the groups he frequented were many neo-Nazis who like fascists in the 1930s and 40s, lionize Swedes as an original "unspoilt" version of the Aryan race.
A great deal of the alt-right movement is crowdfunded. They have crowdfunding sites like Hatreon where they get money for projects or individual events. Recently, for example, a group of European "Identitarians" linked to the alt-right raised more than $200,000 to charter a ship to hamper the efforts of organizations working with migrants trying to cross the Mediterranean to Europe. This money was raised around the world via crowdfunding. In one way, this shows the scale of the alt-right.
