Scott, I ordinarily follow and admire your cool collected line of thinking to the ends of the earth and back, however this quotation seems very much out of character.
"Morality police"?
Methinks it's choice, both business and personal. Police denotes the law, black or white, and that anyone who make a personal stance differs is the "police" as in a very negative connotation.
Basically, I could give a pituitary gland less what one's moral standards are as long as they are not inflicted upon me without my consent. If I object, it can (and would) be done in such a fashion as to make it quite uncomfortable for the perpetrator to do it again. It is just that such a person (as me) that I would fear should I ever acquiesce to actually playing a track with obvious "shock jock" or gratuitous vulgarities.
It is precisely why I choose not to play the I95 song for bridal party introductions even though the bride and/or groom might be the often lyrically referred to jerk.
