I have no idea what you're talking about or who you're arguing with. You brought up the "cold winter theory". "Cold winter" is very funny. It's just a very funny theory put forth by a huckster white supremacist. Where do you hope to go from there?
Whatever the rest of these arguments are, I'm not invested enough in this thread to drag this out.
Cold winters. Tell it to the Abbasids! I guess some of them had kind of cold winters sometimes? Maybe that explains it.
