You'd have a more convincing argument if you argued for a passenger with Tourette's or something. Bodily functions are obviously different from watching a movie at full volume, because there's never a situation where you would be involuntarily blasting the audio of your show or whatever to the whole plane.
Okay, Tourette’s then. Should we kick people off for Tourette’s?
Your comment also presupposes two things: that flatulence is always involuntary and blasting music isn’t. Let’s say I have a form of Tourette’s that forces me to involuntarily blast noise and music and I have medical papers to prove it. Is it okay then?
I would absolutely support it if you could demonstrate that those two things are actually true. My point is: Who gets to decide what’s legitimately an involuntary medical issue and what isn’t, and where is the line that demarcates it? And what is the point of this exercise? It’s to prevent people from forcing everyone else to have a worse experience for their own personal gain, which flatulence is a form of that you could argue, so why is blasting music fundamentally different?
