I 'dialogued' with some local JWs several years ago. I agreed to a meeting and there was one guy, and the second time there were two guys, and third time was at the Kingdom Hall with three guys, at least one of them was in the hierarchy. They pointed to a verse in Isaiah that referred to the 'circle of the Earth'. showing that the prophet knew the Earth was round. I pointed out that circles are flat. We went round and round over that.
I'm not anti-Christian. I'm anti-stupid.
