Who exactly is the advice for? For those who don't read, right? In that case, how does abusing them help? There's another golden rule about treating people the way--can't quite recall it, hmmm...

Casual obscenity has become so normalized in the culture, you probably feel outraged I'm even bringing it up. Not reading has also become normalized in just the same manner. No one reads if they can at all help it-- not at work, not in parks, not on the commute, and not for writing. Their loss, of course.
