So you know what was going on in Ian's head better than he did and would rather call him a liar than accept his simple explanation that explains his behavior quite well?
I never used the word "liar" in reference to Ian. I'm just Questioning Assumptions. Do you work for Newsweek?
It's possible he had alterior motives and you are free to question assumptions all you want. I simply think it's dangerous to select evidence based on a desired conclusion. That's basically called "begging the question" in debates. Do you have any evidence that Ian had alterior motives?
