John, your careful, calibrated, sincere response is such a fresh deviation from the harsh "ad hominem" attack responses I get to my articles. It's amazing how people who don't know one another at all wouldn't mind attacking with all the venom in between their ears. Most people have already made up their minds about everything under the sun and they're just looking for a fresh victim, not a new discussion where they might learn or teach a thing or two. Peace to you, with or without portals. P.S. Yes, I agree. I think you must have read too many sci-fi novels :-)
