And the actual party platform....what they actually did....
The first ten points establish a racial collective state, where members of different races are ruled under different laws. Affirmative Action, in other words. That is so remarkably and obviously leftwing as to need no further comment from me. See Black Lives Matter for details.
11. The abolition of incomes unearned by work.
This refers to interest from investments without which industrial activity cannot be privately funded. This is an implicit call to nationalize all investment. Socialist.
12. We demand therefore the ruthless confiscation of all war profits.
This is an explicit call to nationalize all military supply industries. Socialist.
13. We demand the nationalization of all businesses which have been formed into corporations (trusts).
This is an explicit call to nationalize all corporate industries. Socialist.
14. We demand profit-sharing in large industrial enterprises.
This is an explicit call for state control of terms of compensation. Socialist.
15. We demand the extensive development of insurance for old age.
This is an explicit call for socialized pensions. Socialist.
16. We demand … immediate communalizing of big department stores, and their lease at a cheap rate to small traders…
This is an explicit call for socialized retail. Socialist.
17. We demand a land reform suitable to our national requirements, the passing of a law for the expropriation of land for communal purposes without compensation; the abolition of ground rent, and the prohibition of all speculation in land.
This is an explicit call for communal farms, state control of rents, nationalization of investment in land. Socialist.
18. We demand the ruthless prosecution of those whose activities are injurious to the common interest. Common criminals, usurers, profiteers, etc., must be punished with death, whatever their creed or race.
Note the listing of common criminals with usurers and profiteers. This is the implicit criminalization of the free market. Socialist.
19. We demand that Roman Law, which serves a materialistic world order, be replaced by a German common law.
This is an explicit call for the elimination of the traditional judge-made sources of law, akin to Anglo-American Common Law, in favor of reformers and radicals.
The elimination of Common Law is the heart and soul of radicalism. Socialist.
20. The State must consider a thorough reconstruction of our national system of education
This is an explicit call for a nationalized public school system, to eliminate private and religious schooling. Socialist.
21. The State must ensure that the nation’s health standards are raised by … by prohibiting child labor, by promoting physical strength through legislation providing for compulsory gymnastics and sports….
Laws against child labor are core leftwing crusading goals, since before the time of Dickens. Compulsory gymnastics and sports was enacted into law in Ohio and California after the Civil War, so this one point, finally might be arguably rightwing or leftwing, depending on whether compulsory public education is.
