So the same applies to me. I don't feel that I should have to suffer in silence just for fear that the other person might overreact.
This brings us quite nicely back to a point we've tripped over more times than I can count.
You have the RIGHT to do a great many things which may be very unwise, or which may simply prove to have consequences you were not prepared for.
You have the RIGHT to walk down Gratiot St. in Detroit at 11:30 pm in nothing but a pink tu-tu, wearing 12 Rolexes on each arm and singing Klan rally songs. But nothing on earth makes you immune from the consequences of those choices.
Similarly, you have the right to approach unknown folks in public with all sorts of requests that they alter their actions to suit your preferences. They do not have the RIGHT to harm you ... but they just may do so anyway. The fact that you have a gun and think you can maybe take care of yourself should not give you one more ounce of courage than you'd otherwise have without any weapons at all.
If you end up killing someone, you MAY (or may not) be found justified by the jury which will look at the totality of what happened and will ask what you could have done to have avoided that problem. (And "Stand Your Ground" has much less to do with this than most folks seem to think!)
As I've mentioned before:
Tom Givens' "Lessons From the Street" DVD had a very pertinent story of one of his former students who shot two men in self-defense.
The man was alone in a convenience store parking lot and felt that a group of men present were possibly getting ready to do him harm. He spoke to them, telling them basically to go away. That ticked them off and they then did approach him. He fled and they took chase. He ran some distance away, being actively pursued by six or more men. He turned and fired, hitting two of them.
He was arrested and charged, and ended up sweating out a long court process which ended in, IIRC, probation, and he was quite lucky to get that.
What is pertinent about this to the story in this thread? The "victim" spoke to these men, giving them an instruction or command, which he had a legal right to do (though no authority to enforce), but that was seen as instigation of the events which followed. He had no legal right to fire on those men when he first made contact, yet his actions lead to him shooting two of them. He therefore shared culpability for their deaths.
So remember, if you approach someone in a way that is at all likely to instigate a negative response, you very well may be seen to share the blame for whatever shakes out. Approach someone to tell them to turn down their stereo, or not to loiter, or curb their dog, or to keep down their speed in your neighborhood -- or pretty much anything that might be confrontational, and you are absolutely putting your life, freedom, and fortune on the line.
Just because you are "right" doesn't mean your life won't be ruined...or ended.
Sure...it is reasonable to speak to other people about things that you'd like them to do. But not everyone else is a reasonable person, so do so with your very best social skills in play, feeling for every signal of their intents and reactions, and be prepared to de-escalate with great haste if need be.
Remember, many types of creature -- especially humans -- make displays of action, posture, and countenance to show other members of their society that they are powerful, dangerous, and/or "in charge here." For some individuals, playing loud music in public is clearly part of that ritual display of strength and dominance. They are sending a message, and it isn't that "
golly gee I like this band a whole lot, you betcha!"
As Fred has mentioned the "Monkey Dance," I'll suggest that mildly obnoxious and provoking behavior is certainly one facet of that. By blaring aggressive, deliberately non-universal types of music many actors are making a dominance display, and by confronting them you will be making a (perhaps) unintended challenge to their standing. It always pays to understand what's REALLY going on before you decide to do something "reasonable."
