Note, the vast majority of airline "unruliness" is verbal not physical
The vast majority of motorists have exceeded the posted speed limit intentionally or not. But only a small minority will get into a physical altercation with the police officer that's issuing a citation.
Most airline incidents do not involve physical altercation, yet you could get banned from all airlines?
That would be like getting a traffic ticket and having your license revoked. Typically that happens with repeat infractions
I don't agree with that idea, but that's effectively how things work, you might find exceptions to the rule, but once your reputation is tainted with a legal charge, it follows you forever within society.
*Not literally, but it feels that way/my perceived experience.
Paraphrasing, we are all Americans, we need to remember that though we have different views we have far more in common and we can only get better by coming together.
