"I don't see many "Christian Leaders" placing some of the blame on a lukewarm and complacent church...That is more to blame than any of the other reasons Falwell gave." On the contrary. Many modern churches support the kind of sins that Falwell railed against. You want to abort, practice sodomy and commit adultery? Join the Methodists, Unitarians, and a number of other "Christian" sects.
I don't want to do any of those things. I'm against all that sinful behavior and would never belong to a church that condoned it.
