@dad ,
I noticed that you self-identify as "undefeated" which to me assures that you see threads here as contests and that you will never agree that you made a mistake. If you did, you would have to surrender a confrontational assertion of always being right.
Of course, when people present their POV's or supporting information, they do so because they believe they're right. That's human nature. But the claim of "undefeated" convinces me to state my perspective at times but not to expect a substantive discussion but rather having my point dismissed with no further ado.
