Jonah Goldberg is not wrong about everything in his mostly annoying book, _Liberal Fascism_. Thus, the term "fascism" has been too readily thrown about by many on the left; there were racist eugenicists among American progressives, with Hitler particularly copying the forced sterilization laws first pushed in the US by Woodrow Wilson, and indeed Mussolini was originally a socialist, and Italian fascism in particular had some socialist elements about it. That said, the book is crawling with numerous mislabelings and errors. I note only two here, at least one of which has not been pointed out so far by others.
That one involves the Church and corporatism. Goldberg identifies fascism as being against traditional Christianity. However, the central core economic doctrine of fascism was corporatism. The unequivocal origin of corporatism was encyclicals of the Roman Catholic Church in the late nineteenth century. I will also point out that a core concept held by all the fascist parties was to oppose democracy. Goldberg likes to label the American progressives as "fascist," (including Richard Ely, co-founder of the American Econmic Association), but none ever opposed democracy, and I am unaware of any current US politician who might be labeled a "liberal" who does either (or any who ever was who did). On the basis of these two points, Goldberg's book amounts to largely a partisan screed.
