Mark, can you please respond in fewer threads. This scattergun approach not only makes it impossible for us to keep up with your arguments, it also stops people from replying to earlier threads because they get lost. It might not be your intention, but you hit these threads with a machinegun spray of posts, and the end result is that people can't keep up, lose interest and wander off.
It also lowers your argument by making it look like a stream of consciousness, kneejerk stream of replies instead of a measured response.
