The majority of modern fascists seem to have gotten there from a libertarian to fascist pipeline...largely motivated by respect for freedom of association and anger over the betrayal of woke capital.
I personally was actually a monarchist and came to fascism by the above realization, well documented and explained by the political philosopher and historian Bertrand de jouvenal...and the whole phenomenon of the top and low alliance against the middle and how monarchy incentivizes it.
That was also the monarchist to fascist pipeline in the 1920s....which was the biggest group that converted.
