Saddened to see the Ice-age Columbus thread has been locked and am not sure why - was it getting abusive?

It was getting almost unreadable like others have too because a certain individual has no repect for the theme of a thread. He subverts most topics by imposing his own agenda and every thread then becomes swamped with stuff on dowsing and energy lines etc. Surely the lesson should have been learned with Mike - you don't need to ban people - you just ignore them. The more you respond the more their ego is puffed up and the more nonsense they spout.
