Moose,
I think Whatever should be allowed back in. I don't think he should've been banned outright in the first place. If the plan was to allow a cool off period then maybe the relevant threads should've been blocked for a day or so with a warning to Whatever.
He IS immensely irritating because he is such an inconsistent compartmentalised thinker, but I don't think he's a troll. He needs to assimilate what he says at any point into everything else he believes & check for inconsistensies. He also needs to read replies thouroughly before responding. I lost count of how many times I had to reiterate the same Cambrian-explosion-wasn't-affected-by-the-flood point before the penny finally dropped.
