We get it - you're justifiably ticked by the stupidity of the existence of USAPA, I don't disagree with you. That said, if an idiot says something profound it's still profound, and if a wise man utters something foolish it's still foolish. All I know about this is the little I've read here and online, but it looks to me like USAPA at least hit a double on this regardless of your personal feelings about them. This seems to be bigger than any one pilot group or union, this speaks to the authority of the captain which has been steadily eroding for the past decade or more. If there is any substance to the claims of USAPA, then they have done a good thing here.

If anything, security should have hauled away the gate agents for interfering with an aircrew member performing their duties, unless she was relieved by appropriate persons listed in the company's AOM/FOM or whatever Useless Airways calls it, and then that person should have been named in the ad.
