Can you say, "Wrong focus"?

In Europe, such movies [previews that contain violence] are rated X because of violence. In the United States, an X-rated movie contains profanity or implicit or explicit sex. We are disturbed if our youngsters are exposed prematurely to sexuality on the screen, but we virtually ignore the effects of disproportionate violence that dominates almost every set of previews of coming attractions.—America and Its Guns: A Theological Expose, page 34

What's with our love of violence? We label a movie R because of profanity, but we'll allow a PG-13 or PG that shows murder? What's up with that? As if swearing is worse than killing?
