Then what ARE you saying? It is unclear to me.

I suppose that arguing that someone is NOT a crackpot is like arguing
for the innocence of someone in court, i.e. it is very difficult. It
makes more sense to argue for the guilt of a suspect, and similarly it
is easier to say why someone is a crackpot than to say why someone else
is not. I meant that I have seen no evidence to indicate that he is a
crackpot.
