I said I'd shut up on this site but now that so many others have ignored tink's plea that we avoid being 'negative' (i.e factual and rational) I reckon I'm free to rejoin.
Yes, tigerlelly, naomi and flip_flop, we have certainly been here before - witnessing the gulf between those who advocate an open mind on a wide range of unsupportable things and those who favour analysis and a proper use of discrimination.
The trouble about the 'open mind at all costs' idea is that anyone can moot anything, no matter how absurd, far-fetched, and weird, and all the rest of us are obliged to be open-minded about it unless we can disprove it. Well, I'm sorry, but I am not prepared to keep an open mind about the existence of Santa, fairies and the rest.
To say "This makes no sense, it defies all logic and natural laws, there is not an atom of evidence to support it, therefore it is rational to dismiss it until the situation changes and evidence appears" is logical and sensible. Alleged psychics can be so described and dismissed.
Having brains which can reason is the huge advantage evolution has given us over the other animals. Not to use them is a waste.
