“Its racist to ask them to turn their music down!!!!!”
LOL I simply open my windows and blast the Christian music station right back at them. (OK—so it’s not a very Christian thing to do)
Since the stereo in my vehicle cannot compete db-wise with the very expensive sound systems that can make driving a living hell, I don’t even try. Instead, I egg them on. Hollering “Louder! LOUDER!” and making hand gestures indicating a desire for the sound level to be increased while grinning amiably can sometimes have positive side effects. Long term, possible deafness for these auditory miscreants, and on one memorable occasion, I goaded them into turning the volume so high it blew their speakers. My ears buzzed for two days, but it was worth it.
