Me: You're confusing two different things ...
Him: No, I'm not confused at all. See, this is why I say that once you start disagreeing it's a waste of time to try to communicate with you. Or at least too upsetting for me to want to engage in. You rapidly veer into putdowns and insults. "You're confused" is an insult. "I have the following different way of looking at it" is a constructive disagreement. See the difference?
Me: I didn't say you were [confused]. "Confusing two different things" and "being confused" are not the same thing.
Him: Stopped reading after this. End of discussion. Thanks for what information you did provide while it lasted. Unfortunate to be reminded of my problems with you. Oh well.
This really bothered me. (I lost sleep over it in fact.) So I need a sanity check. Is it really an insult to say to someone, "You're confusing two different things..."? Or is this person being overly sensitive?
