I understand that you are just being difficult and obtuse since I assume you are bright enough to understand that individuals can agree with others’ ideas without specifically citing that person. Think of Buchanan and Fulani’s ideas as a Venn diagram with significant overlap.
No, you are the one being difficult. You began by spreading one lie about Buchanan—that Fulani was his running mate—and then, when confronted with the truth, began spreading another, that there was considerable ideological affinity between Fulani, Buchanan, and Sam Francis. You have produced zero evidence to support this second lie, unless an attack on Buchanan produced by a far-left outfit is considered evidence. (By the way, the person behind the analysis you cited is Chip Berlet, a former vice chairman of the National Lawyers Guild, which was established as a Communist front organization). In fact, you have not demonstrated that you are actually familiar with the works of Buchanan and Francis. I invite you to read them: they contain more insight than anything produced by Chip Berlet and his fellow travelers on the far left.
