While this is a sloppy way of saying it, and I don't entirely agree with the application, I have to admit this comment reminded me of I Corinthians 5:9-10 "I wrote to you in my epistle not to keep company with sexually immoral people. Yet I certainly did not mean with the sexually immoral people of this world, or with the covetous, or extortioners, or idolaters, since then you would need to go out of the world."
Excellent point.
