Question. Why are you arguing with youself?
I don’t see how you arrive at the conclusion that Williams is “arguing” with himself.
Your post was in reply to Williams’ post #6, which was a reply to Cathi’s post #1.
If Williams’ post #6 — which you replied to with the comment he was arguing with himself — was actually a reply to Cathi’s post #1, how is that Williams “arguing with himself?”
He also has posts to Cathi on #3 and #4, but those are simply additional comments to Cathi.
He is — rather than “arguing with himself” — merely adding comments to Cathi, possibly comments he had intended to make on a previous post, but didn’t.
I think you are assuming facts not in evidence.
