Judges would decide this like they do other questions of law.
Seems like a lot of undefined words like “dangerous” just like the law. How is it “dangerous” for example, if I refuse to wear a mask? That’s a pretty law bar.
And here is the real issue. These white Trump supporters who refuse to wear masks? Fuck 'em. Ban 'em. That’s not what the law is for is to enact one’s own political preferences into those words.
And what facts are you using to support the accusations? “Bettering a flight attendant” Was it a typo and supposedly to be “belittling”? Then it is sober up and fly with us later.
“Putting others in fear for their life!” That is definitely serious, but give me some examples. I would support a ban if someone threatened to kill other passengers, but not just because someone is acting like a dick. That action does not support your hysteria.
