The OP probably had reasonable suspicion that the screeners were idiots. The screeners confirmed that suspicion when they called an LEO to investigate the OP's use of the word "idiots" at the checkpoint (something even the idiots in charge of the TSA have yet to explicitly prohibit).

I'd say the OP's spidey sense was dead on that day.

As an aside, then a worthless LEO "lectured" the OP and asserted that the OP could not call them idiots. Hat trick.
