You have to forget the notion that you can defeat fascism by reason or because your ideas are right and good. The argument for fascism is not a rational one, but a value judgement that is irreconcilable with any value we would hold dear. You can debunk their facile arguments all day, but they will just invent new ones. As it turns out, their core arguments are largely supported by a lot of institutional ideology, though again a faulty understanding of "fascism" obscures just how common their ideology is. Too many people assumed fascism was goose-stepping and faggy uniforms, but that was merely the window dressing appropriate to that historical epoch. The sympathizers of Hitlerism did smart to find ways to worm into the culture, and it started immediately after WW2 as Nazi intellectuals were rolled in to the anticommunist crusade. Slowly, they were able, with the assistance of liberals weary of the public's demands, to normalize the assumptions and premises on which Hitlerism operated, while officially proclaiming that they reviled Hitler. One of the earliest PR coups indeed was to paint the Nazis as a historically unique aberration, and to pin all of the Nazis' excesses on Hitler's character, while any deeper understanding of the thorough degeneracy of the fascist movement was suppressed. The rise of fascism was turned into a moral fable about Hitler's meanness towards the Jews, conveniently stripping away American and British complicity in letting the Nazi takeover happen and the sympathy of many prominent American industrialists and financiers. Such a course of action was necessary, because too much honesty would expose the crimes of American eugenicists, and if left unchecked it probably would have led to prominent eugenists being publicly lynched by a mob. It took a great deal of FUD and misdirection to divert an angry public away from these people who were quite visibly worming their way into the culture. By 1970, the project to rehabilitate eugenism and the Nazis was in full swing, finding a ready ally in social imperialists who would claim these policies only applied to the Third World. By 1980, it has ascended into the popular consciousness through one of the most complex cultural infiltrations in history, and by the 1990s it was going utterly apeshit and prepared the ground for a full-on assault against the poor. Every crisis since then has come ready with plans to destroy what liberty the lowest classes had. In the long run, the only way to sustain this push is to move more and more towards overt Hitlerism, because the norms of liberal government - like, for instance, something resembling fair trials, due process, or the ability to appeal to representatives - would stymie the progress of the most egregious measures, those that go beyond the pale even after all of the indoctrination and normalization of the utter depravity we see today.
