So, you condemn the man for smashing the phone, but then you say you don't know if you could control yourself not to punch her? You're talking about actually applying a physical force to a woman! How could such a thought even cross the mind of a man? It's pathetic.
Well, obviously, that was a throwaway comment, exagerating the amount of anger I would feel towards her, or anyone else in that situation, regardless of gender, and the inability to control myself, for comedic effect. I could have said, "I would have punched her".
(.... ooh, now you are back-tracking, you violent crypto-misogynist scumbag, you...)
Then you say he had no right to do it and caused a scene, but you are perfectly fine if the management did precisely the same. So I wonder, on whose authority would the management be acting when destroying their patrons' private property.
Who said anything about management destroying someone's phone? What possible justification could there be for that....?
