A possibly large portion of people who are aligning with fascist ideals are doing so not necessarily because they wish to, but because they see no other choice.
As increasing amounts of pressure are heaped on the quiet, primarily white portions of the world, people are quickly finding whatever bastions of safety shrinking and under active attack. Initially this was very obvious, with changing city demographics, school curriculum and the like, but the slow creep in to entertainment is speeding up year by year. There are fewer places to stand, live, or laugh where you are not under the scrutiny of those who hold themselves to be the arbiters of the new era of decency.
Some hop to the fascist side because it chaps the ass of those above, but there are many who are all but pushed to it. If one loves their country, wants to feel safe at home and work, and generally wishes to be left alone, the roar of the media and the new lords of justice state that they are a nazi. There's pushback, sure, but eventually people throw up their hands and embrace it, if only to stop the argument.
Fascism isn't, by itself, wrong. I agree with many fascist ideals, but it's hard to just toss aside the core structure of one's own country. However, as the ideals of the west, and christianity, are eaten away at with the roaring cheers of those who hold themselves to be the lords of the future world, the quiet lurkers are forced to make a choice. Follow along, and vanish beneath the waves, or hold to anything that might give a chance to survive. Too many are forced to come to a simple, cold conclusion of logic:
We're dead anyway, why not try to go down fighting?
