Really? I usually had adequately civil exchanges with him, because I police myself, but I don't feel he's a loss to the general exchange of useful knowledge, by any means.
Reading his posts actually prompted me to join FR - he was supporting the smoking ban here in Ireland, and he even wanted to "eliminate smoking" altogether - I decided to join up to tackle him, but it took a while for my registration to come through in the email...
I tackled him on another thread a few months ago where he referred to Northern Ireland as a 'theocracy' - his anti-Christian bias knows no bounds.
He had all the hallmarks of a troll.
