I have had people tell me, when I am found wrong, you can just tell me, "I told you so". But, I have never uttered those words.
They are never helpful.
Further, it is our govern-cement school indoctrination that puts us at such odds with the truth. "Lincoln freed the slaves" is what they were taught, and if they repeated that, they were a good boy or girl. So, challenging that is literally calling them a bad boy/girl.
I have found you to be very self-controlled in our discussions; you may be immune or less affected by some of these impulses.
society ->government -> control -> individual
like I said, groupthink is the normal human pattern
oh yes, kills that feeling of belonging
