Our own moose and a couple of others tackled him on this and Terry eventually conceded. Nevertheless, this one post, I think sums up Terry's thought processes in a nutcase.
Do you have a link? I don't post on Terry's board but I do occasionally read posts over there when they get linked to, here. He strikes me as kind of arrogant, so I'd like to see him conceding something.
I imagine your objections to his post was the fact that walking "upright" means walking with one's spine on top of one's pelvis, right? A posture that not too many animals are capable of - certainly not the ones Terry mentions.
