As for me tossing you kudos, you know I have vehemently disagreed with you and your delivery at times

Oh well, we all make mistakes, bwahahahahaha!!!

Seriously, though, nothing bad about disagreement, per se. In fact, that helps shed more light on the topic, by opening up a discussion about it. When we're surrounded by "yes men", we're just playing "Emperor's New Clothes" while remaining as unclothed as before.

Where I think there's a problem is when people disagree because they'd have issues to otherwise face if they owned up to it, which may be uncomfortable or unpleasant, so they mask it behind their premises, fighting over a topical issue instead.

As an example, in my sitch, my wife used to routinely place what she thought others would feel and think over what I felt. The fact is, that if I'm her partner in life, my feelings should be considered, right or wrong, over that of others outside the relationship. So the question becomes, why did she have that view? The answer turns out to be, she had a low self-esteem, and so the perceived assumed opinions of others were paramount to her. But that has a lot of destructive factors to it: it involves her assuming what others would think; it minimizes how her mate feels; it jumps to conclusions of what the consequences would be; and then, if any of those consequences are realized, the blame got shifted to me. IOW, now I'm being blamed for what others choose to do. As a result, it chips away at the bond between us.

Instead, the issue was really that she had a fear of how she unduly assumed she (or we, or I) would appear in her friend's eyes. I think if she had stepped up to the plate, though, and we could have a better discussion without these factors, a better resolution could come out of it instead of a worsened circumstance. But it's easier for someone to cling to something than it is to let go and do the hard work. Now, as a disclaimer, let me say that for the purposes of my illustration, I'm just talking about her part in this dynamic, I do understand there was my part too. But does this make sense?
