It seems to me there are two things you might respond to:
1. He described some of your comments as lies. Is he right?
2. More to the point: I think it is obvious that your style, over a series
of postings, has deeply offended a fellow brother in Christ. Without
trying to offend you in the process, I would respectfully suggest that
what you call "sour grapes" is really an expression of legitimate "pain"
on his part. You do have a VERY aggressive style. One response would be
to apologize.
