I didn't see him as demeaning your talk. What he was clearly saying is that he didn't believe your talk. I agree in that I think you talk a little tough occasionally to have a little "street cred" and not come off as a 100% DALPA apologist. But in the end, you always come around to the 100% alignment with DALPA. That's what he meant when he said this:

Now you on the other hand stooped to the standard DALPA tactic of disqualifying someone's opinion because you made the (wrong in DAL88's case) assumption that he'd never done any work in DALPA...and only talk:

That was very alfaromeo of you. It's not flattering.
