Mims was the only person claiming to attend the meeting who made these statemsnts. (There was another claimant, but she referrenced Mims's stuff only.)
Several other attendees disagreed with Mims's comments. Perhaps Creationists feel that Mims told the truth and everyone else is lying.
Dr. Pianka's talk at the TAS meeting was mostly of the problems humans are causing as we rapidly proliferate around the globe. While what he had to say is way too vast to remember it all, moreover to relay it here in this blog, the bulk of his talk was that he's waiting for the virus that will eventually arise and kill off 90% of human population. In fact, his hope, if you can call it that, is that the ebola virus which attacks humans currently (but only through blood transmission) will mutate with the ebola virus that attacks monkeys airborne to create an airborne ebola virus that attacks humans. He's a radical thinker, that one! I mean, he's basically advocating for the death of all but 10% of the current population! And at the risk of sounding just as radical, I think he's right.
