Can a passenger force a Go Around?
Not likely. Pilots wear headphones, so we cannot hear the idle prattle of the pax in the hold. In any case, we don't take orders from passengers. Think about that for a second: would you like it if aircraft pilots followed the instructions of a crazy screaming passenger? What if there were TWO crazy screaming passengers giving contradictory commands? Which one should we obey?

In any case, nowadays cockpit doors are closed during flight anyway.
