To this point, there have been at least a few stories of elderly people being beaten on San Francisco public transit for politely asking people to turn their music down.
Public music should be celebrated. This is someone sharing a cultural touchstone and y'all just want to be antisocial robots.
I don’t drive, I take public transit daily, and am old enough to remember when you would never experience anything like this (even in the heyday of boom boxes in the 80s). So yeah I’m not convinced it’s a “me” problem.
And returning to the point, if you asked someone 30 years ago to turn their music down they would either comply or say something nasty - not physically assault you.
