How about taking the full quote, and defining the terms in that full quote? Otherwise you’re just straw-manning based on cherry picking.

Threats in airplanes, post 9/11, land different. “Free D.C., Fuck Americans” says something different to fellow passengers than “Free D.C.”.

Not crazy, not bonkers. Yes, a threat. And in an airline context: they are all treated as credible… that’s why your shoes get checked, and water gets stopped, and babies banana smoothies get confiscated because of potassium content.

Plus, there’s a red line from the PLO and hijackings through 9/11 to the current state of airline security. That’s not neutral, and not incidental, for an airline that knows recent history.
