I've worked as a flight attendant for 35 years for one of the world's largest carriers, so I'm familiar with company policy. On numerous occasions I've had to cite chapter and verse when passengers refuse to obey the rules.
If noncompliant passengers believe the highly transmittable coronavirus is a hoax or that refusal to wear a mask makes some political statement or that their rights are being assailed, they are entitled to their opinions. But not at 30,000 feet. Not in a confined space for hours at a time with hundreds of worried strangers. Not when social distancing is impossible to achieve.
Wear a mask and get over yourself. If the Earth revolved around you and your sentiments, it would spin off its axis. And there would be no place for us to fly.
