Angelo John Gage is a professional lifestyle coach (professionally certified as such by Tony Robbins' self-help organization). He makes money running a service teaching what professes to be "self-improvement" and dating advice. His money and income are literally generated by not being an incel and exploiting incels into believing that if they hate jews enough then they too will not be incels; since the primary qualification is "not being an incel," approximately 95% of all men are as qualified as Angelo to make money in that manner, but Angelo manages to be a member of the elite minority of men who transform socially predatory moral depravity from a hobby to a profession.
That means that Gage supporters fall into two categories; morally bankrupt would-be scam artists who see the end result of promoting Nazism as justifying the means of scamming the lower orders of man out of their pitifully small reserves of money and happiness, and unusually stupid incels who fall prey to such scams.
It is honestly shocking to see how many white nationalists will support any scam artist so long as he promotes racism; when con artists are exposed in movements filled with honest men, the honest men will generally exile the shyster to preserve their own integrity. This happens even in large-scale elaborate cons, such as organized religion. But not only is Angelo John Gage not the biggest fraud in white nationalism, he is also not the most important. David Duke himself defrauded his own supporters out of a considerable amount of money–more than some of his uneducated and underemployed fans could afford, which is why they bothered to take their case to the courts. Duke is one of the surprisingly numerous instance of white supremacist leaders who went to prison not for harm done to blacks, but to his own white nationalist followers. The only time I am aware of the alt right actually refusing to support one of their leading con artists was the case of the Nazi leader who led the march on Skokie, Illinois, who went to prison not for any of the neonazi racist activities he was promoting, but for using his connections with his Nazi group to molest underage boys. If it had just been their money that was stolen instead of their young relatives who were sodomized they might never have turned on him.
