From reading much of his Answer-in-Genesis quotes over the years and his historical disagreements with his own kind, plus his actions that took him to the helm of AIG.
The former (USURPER) appears to fit.
He evidently saw Creationism as being a great con and chance to gain easy money and power. Thus the political power-play cards he dealt against his own Australian creationist group.
Evidently the USA is a much better market, with a lot more stupid sheep to fleece. Also, because many of his statements over the years can only be perceived as lies or twisting and dodging contention to pretend creationism has truths.
On the other hand, the seemingly most unlikely case is that he actually believes his own blatant, twisted lies and stupidity, in which he would have to be one of the most idiotic, naive loons on planet Earth.
I think he's in AIG, because it reaps bigger rewards than being a lowly, not very good teacher, much easier to be a Creationist usurper.
Most of the scientists who turned to writing Creationist material are likely on the same wagon, more money and recognition in usurping extremely dumb Creationists for the contents of their fat wallets, than trying to make it as an average scientist. The retirement benefits are far better!
What do you think M8z?
