If the Saudi Muslims think it necessary to build a wall to keep out Iraqi Muslims to the north and Yemeni Muslims to the south why should we doubt that they have a very, VERY, good reason? If Muslims are willing to mercilessly murder EACH OTHER, just WHY on God’s green earth would we want their unchecked barbarism freely pouring into our country? When your pursuit of happiness ends in the merciless murder of innocents, you need to be utterly barred from a place where you are free to exercise it!!!
