Terry; all this "thinking" you're doing is *really*bad*. I appreciate that you believe you're trying to "educate" us somehow. But what you're really doing right now is filling our list archives with convincing-sounding crap. People that are curious about this issue are likely to turn up your postings, and get *really* confused. Please. Just stop, ok? -- ... every activity meets with opposition, everyone who acts has his rivals and unfortunately opponents also.
