Yeah, but that "path to greatness" is an uncritical idealization of a certain narrative, in your case that being borderline fascism. It's pure Romanticism (the art of seeing everything in rose-tainted glasses), like people who believe that war is a matter of glory and honor for the Nation—clearly haven't been in one themselves, nor read anything about the thoughts and life of the common soldiers in the battlefield (I recommend you read "All Quiet in the Western Front", which is about German WWI soldiers), but the fat generals on the rear guard. That's what killed nazism and white supremacism for me, and one of the reasons I left it. It's a way of looking at the world that is black and white (pun intended), and completely ignorant of all different variables and different styles, and all the "shades of grey" in the universe and our society. It chooses emotion over critical rationality, and therefore it can't be combatted with the latter. It's self-perpetuating, and tries to shave off criticism by imprisoning the opposition.
Killing, deporting and/or exiling every african american, muslim, and latin american, isn't going to solve the problem with american capitalism, it was doomed the moment global capitalism started to liberalize and companies started to flee to countries where they could pay no taxes and give incredibly shitty wages to precariated workers, thus initiating a "race to the bottom" for more developed countries. Those groups of people are merely scapegoats with what is a systemic issue, that is also idealized upon (capitalism). The incapacity to rationalize and understand such a situation is due to the idealization of people who can't know better because they are closed in in their world of resentment for the situation; that's why fascism creates strength when the country is getting shittier, something that it has in common with socialism.
I'm an existentialist. I believe that there is no meaning of life and anyone who claims to hold it, is inherently wrong. The only real "meaning" there can be, however, is the one you construct yourself. In existentialism, you create your own meaning in the way you choose. I strongly suggest you watch this video from Crash Course Philosophy on existentialism; there is also the religious existentialism of Søren Kierkegaard, if that's what you would like more.
