Did you have anything useful to add?  You say it "deserves to be
treated as a question of fact", but you make no attempt to do
so yourself.

You seem to be dredging up old posts of mine (this one is from
about 10 months ago) and finding reasons to complain about them,
usually because the fact that I expressed an opinion bothers you.
I encourage you to knock it off.
