There is no point in engaging with Keith because he is deeply unwell and can't help himself. While I can understand mental illness I don't understand why Dave allows one disturbed individual to ruin the invaluable resource that he has spent decades of effort creating for us. Perhaps Dave should revive the Misfires subforum, rename it Keith, and allow him to post nowhere else. Then he and those who enjoy engaging with him can have at it while the rest of us talk about double guns.
