"Your comments to me and their fairness or lack of are evidence that can be interpreted."
You can't come to an informed decision based on a single conversation that is missing blatant forms of stereotyping. Simply put, you lack an acceptable sample size to compensate for the possible variables. Implying that I'm being sexist based solely on the coincidence he and I appear to be male and you appear to be female (it IS the internet after all) is an absolute textbook example of inaccurately assuming the motives of others.

At this point, I see no more reason to continue this off-topic conversation. If you want to debate some of the on-topic points, I'm game. My opinion in a nut-shell. I think the airline was in the wrong for kicking customers for their internal interests. I think the customer was in the wrong for refusing to leave the plane. I think the officers that handled the situation made several mistakes. Customer may have been in the wrong too but it didn't justify the assault.
