I'm not in agreement with Warren on stopping the LHC and never have been. Some of his logic is shaky, but heck so is mine! I do feel that Warren has every right to be scared though. He is requesting prudence in the undertaking of unknown scientific experiments(yeah yeah nature cosmic rays etc). Accidents can still occur, ie. a magnet mount snapping or whatever unrelated to the actual experiments. CERN has not guaranteed 100% safety. If Warren feels that a 1 in a trillion trillion odds of a catastrophic event occurring is too high odds for his comfort he has every right to speak up and protest. So please guys, knock his science around a bit like you did to me, no problem there, but don't knock his fears. His arguments at times have been irrational, but not paranoid or delusional. If he has felt the need to shout and use caps and colors it's no doubt in frustration to some of the responses I myself have seen posted and a sincere attempt on his part to express his concerns.
Another of my usual brilliant analogies(although personally true for me). I don't jump out of airplanes, because I don't like the odds of my parachute failing even with a backup parachute. Noone can convince me with all the statistics in the world to do so. Warren doesn't want to jump out of this airplane, and I am cool with that. He's kicking and fighting the whole way because someone else is shoving him out of the airplane without his consent, and I don't blame him.
Peace out Warren and fight the good fight. I'm on the other side on this, but I respect your struggle.
