This posting from a far-left website proves what exactly? That the far left hates Buchanan and doesn’t think anyone should support him? I could have told you that. What you have not shown—because you can’t—is that Buchanan and Francis endorsed the ideas of Fulani. In their writing, you will see plenty of references to such eminent conservatives as James Burnham and Russell Kirk. You will see zero references to the ideas of Lenora Fulani.
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.
