So how would you accomplish this?
While the moral-liberal producers like to rant about their supposed 1st Amendment rights to ridicule and slam religion, given an organized campaign to contact their sponsors and complain, these oh-so-principled free-speech-at-whatever-cost ideologues would turn around their sleazy content really fast. You and I are eventually paying for this outrage by the products we purchase. If they want to manufacture toothpaste and deodorant and cars, fine. If they want to slam religion and asault our senibilities in doing so, then let them sit on their products and find a better avenue for salesmanship.
Even a handful of letters written to the sponsors of degrading television shows would have a huge effect. Business hates controversy. It gives them a headache, which they want to avoid. Besides, if we were to allow these degenerates to rule the society as they have the culture, there'd be no one of any productive worth out there to buy their products. So really it's all in their own best self-interests, too, to heed our kind message.
"Not allowing" them to broadcast what you find offensive suggests a government prohibition of free speech, which we both know is a no-no.
