Yes because an entire car of people are sitting there, minding their own business, and someone approaches them and violates their personal space. If someone grabbed you with the intention of disturbing you, would that not ruin your ride? How is someone entering your personal space by being loud and obnoxious any different?
Not sure I understand your point? They’re not talking to you. They’re yelling in a crowded subway car. Can you explain how yelling at you vs. touching you are fundamentally different? What if they smell really bad? Would you consider making you smell a foul smell a violation of your personal space? What if they could somehow make you taste something against your will, would that be a violation of your personal space? Not sure why you’re treating ears differently than the rest of the body.
