I have searched for the philosophy behind such a label but terms like "far right" seem only exist as a pejorative by conformists for superficial reasons.
When you study the difference views of big government totalitarinisms like progessivism, identitarian philosophies like nationism, the differencce between Marxism and socialism, are Lenists-Stalinists necassarily communitists, how national socialism always leads to genocide and mass murder.
On the other side of small restricted government, the differences betwedn lft libertarianism vs right libertarianism, the differences between libertarian and conservative, there seems to be no such thing as "far right" except for being strictly leftist identarian tactic because everybody on the political right views government as the problem in society, and everybody on the political left wants to expand government authority. So do the groups listed as beinf far-right want to expand government regulations or do they want to cut and fight the government?
What original sources for literature have you read and historial documents to people in their own original words?
100% of every argument you said furthers the evidence that the term "far right" is strictly a leftist perjorative from highly emotional people and does not exist
