Easy to shut down someone by calling them a "bot." (Reminds me of shutting down people by automatically calling them a racist or whatever.) Although I disagree with Ralph on many of his posts, he is certainly not a bot. Just read his many posts and if you are honest, you will have to admit he is not a bot. As to the rest of your reply, I am not "casting about for explanations" at all. Unlike you, I don't hold a monopoly on the truth.
