I have the typical comment policy — no profanity, etc.
I do hold those who claim to be Christians to a higher standard, and have borrowed Carlotta’s policy on that:
For Believers – An intentionally different standard applies to those who name themselves followers of Christ: persons who claim to be believers in Jesus Christ yet bring manifestly false teaching on basic doctrines of the faith, and/or promote evil acts are not welcomed into discussion here.
I do make exceptions at times, such as when false teacher Chuck “Jesus is not the only way” Currie comments. That’s always fun. But he’s so transparently fake that I don’t worry about people being mislead by his false teachings. Same thing for confessed fakes like this, provided they don’t comment too often. I enjoy pointing out their egregious errors but I only have so much time.
