The skeptics are usually right. On occasion, conventional medicine may be even more stridently wrong than alternative medicine. Skeptics have usually proved that amazing results have far simpler explanations. Crop circles are a prime example; one needs only some simple devices to create a very impressive circle. So why waste some good crops to make the point that we have had alien visitations? Ghosts? Typically they appear in houses less than airtight -- and they are usually animal in origin. UFO's? Count me among those who have seen flying lights that I did not fully understand. Of course those were in the direction of either (Dallas) Love Field or Dallas/Fort Worth Airport. Maybe Addison Airport in northern Dallas -- rumors were that much dope was being flown into that airport before the DEA stationed itself there. Big deal. I'm no expert on aircraft. Oh, yes -- I have seen Venus and under some freakish conditions Mars in daylight.
The Loch Ness monster has been debunked. Sasquatch? In some horrible ads for meat snacks.
The greatest evil is not now done in those sordid "dens of crime" (or) even in concentration camps and labour camps. In those we see its final result. But it is conceived and ordered... in clean, carpeted, warmed and well-lighted offices, by (those) who do not need to raise their voices. Hence, naturally enough, my symbol for Hell is something like the bureaucracy of a police state or the office of a thoroughly nasty business concern."
