Pastor Bathfire's exposition on the Sermon on the Mount guides me not to engage with this willfully vexatious person, but to respond simply:
“Yeah, whatever, you believe that, you’ve sure convinced me, boy.”
Matthew 5:25 Agree with thine adversary quickly, whiles thou art in the way with him; lest at any time the adversary deliver thee to the judge, and the judge deliver thee to the officer, and thou be cast into prison.
Not that I expect to go to prison for disagreeing with this one.
