Oh we will stop arguing about it, as soon as God belief are used as a basis for making special exception to laws, making laws than influence other, supporting wars, interfering with scientific research, restricting freedoms, and choosing politicians.
Notice I, or anyone here, doesn't spent much time arguing over the existence or word of a Kumiho, and can you understand why? The belief of Kumiho, and many tail fox-spirit god of Korea, doesn't affect our lives. The belief in Yahweh DOES.
