There are plenty of places where the Islam is either universal (otherwise you get your head chopped off, including if you go to the wrong mosque) or the overwhelming majority. It has not always been so. Egypt for example or Kazakhstan have not always been of that persuasion. At some point the koran was imported, its principles applied and whatever was there before got subsumed into a sub-caste of infidels. That pattern has not changed in over a thousand years. All the nations concerned have something in common, you'll find if you visit.
Satan saw how well that worked and is now trying the same strategy in Texas. I could not find a list of explicitly witch/warlock/necromancer based nations so Texas must be the first to get this treatment. Witchdoctors say they work AGAINST witchcraft, not by USING witchcraft. If you've ever met one, they are the most obviously demon-possessed persons imaginable and whatever they say they're doing, its effect on those regions (often just one or two villages) is catastrophic. A road trip from Kruger Park up to Entebbe would provide plenty of examples. Satan wants this for Texas.
III John 1:11 Beloved, follow not that which is evil, but that which is good. He that doeth good is of God: but he that doeth evil hath not seen God.
