It appears that I was ahead of my time. As a freshman in high school (well before anyone postulated the "horseshoe theory), I wrote a paper (not as a class assignment but for myself) in which I I concluded that the commonly-regarded "two ends" of the political spectrum not merely formed a horseshoe but, in fact, a complete circle.
The real spectrum is between totalitarianism on the one hand and the constitutional rule of law with democratic elections and freedom of choice on the other. But these are better represented as opposite sides of a circle than either a straight line or a horseshoe.
Fascism and Socialism both oppress people in totalitarian systems, regardless whether it is popularism on the left or right that draws people toward one of these views. Both draw people into regimented movements where freedom disappears.
This is why Orwell's "1984" could be describing either a Communist or a Fascist government. It does not matter: personal freedom has been destroyed in either case. There is only the will of a dictator that everyone must obey, whether that is termed as "the collective good" or whatever. So whether you go to the left or the right, when you move away from a constitutional republic, you end up in the same place.
And on a practical level, I would say that anyone who cannot see the similarity between Antifa and the Nazi Brown Shirts is biased and blind. Antifa may be opposing what they call fascism, but their violent intolerance of anyone who disagrees with them means that if they had the political upper hand, they would impose their ideology just as rigidly as any Fascist or Communist government ever has, most likely under the charisma of a leader who would rise to the top and become a Big Brother.
It is also worth remembering that Nazism stood for "National Socialist German Workers' Party." The only thing that separated German "National Socialism" from Soviet Socialism and the borderless, globalist socialism we are seeing today was pride in their nation and race and the fact that some private ownership of property was retained, as long as it served the national interest.
(For those not familiar with it, the horseshoe theory asserts that the far left and the far right, rather than being at opposite ends political spectrum, in fact closely resemble one another, much like the ends of a horseshoe. This view tends toward the view I proposed except they didn't close the circle.) https://en.wikipedia.org/wiki/Horseshoe_theory
