You are the airline guest until they decide you are not.
At which point you are at least trespassing, and probably worse because it’s commercial aviation.
You agree to their terms when you purchase a ticket.
Indicating that you sympathise with terrorist while on an aircraft should 100% result in law enforcement getting involved.
Which causes that have extremists are okay? Or you're saying all of them?
>You are the airline guest until they decide you are not.
So?
Sure, an airline can legally ban you for whatever reason they want, including blaming you for bad weather if they want.
None of that makes it reasonable or protects the airline from reasonable criticism of their actions.
"It's legal" != "It's okay"
The Westboro baptist church has a legal right to go to a public place near a gay person's funeral and picket "God hates Fags"
They should still get serious flack for it, and genuine resistance. Hell, they literally do it so people will beat them up and they can take them to court (as the family is mostly lawyers)
"They didn't break any laws" is the most pathetic defense. You are saying "But the government won't literally take me away and put me in prison for what I did"
So? You are still a shithead.
>Indicating that you sympathise with terrorist
This did not happen.
> Indicating that you sympathise with terrorist
But that isn't what they did. And even if they did, sympathizing isn't being a terrorist yourself. Law enforcement has nothing to do there, unless you're in a totalitarian state.
