I had a flight out of a major liberal whackjob epicenter and I had a woman next to me who was probably about 50% invested into that attitude/persona. And she was still problematic. Fortunately it was a quick flight and I feigned sleep in my luxurious aisle seat while she caused problems with the civilized passenger next to her who was trapped in the window seat. She had the middle seat.
Side-note: This airport was literally 99% third-world Americans staffed. I've been to dozens of 3rd-world countries and their staff and employees are professional, pleasant and get their job done. However, in the US.... get ready for some barnyard special action going on, backwards service and delays out the yin-yang!! And, oh, don't forget the attitude you'll get if you're civilized and dress like an adult human being.
