Again this is part of Spencer's thesis: That "islam" was concocted by early rulers to unite ethnically diverse factions of their new empire under one common religion. Constantine tried much the same thing when he began to suppress the various forms of xtianity at Nicaea into one over-riding dogma that everyone agreed upon. Of course, it was Theodosius who later implemented what the early Arab caliphs did with Islam. "Believe like I do or die."
Very fucking godly.
Very fucking godly.
