Okay, so I picked this post, because this is where my questions lay.
You say he is sowing discord. Is he? What I see is those who believe as he does pat him on the back so much I'm surprised hands or his back aren't bleeding. Then you have those of us who keep/kept trying to get him to see where he's just plain wrong. And then you have those who are busy thinking/saying, "Ummm, huh?" in different ways.
Now I picture this sort of like a hair braid with three strands. It keeps weaving the same way each time. But I picture discord as braiding but simply ignoring one of the strands, so the end product is... well, messy -- getting no where fast and kind of falling apart.
I don't see any discord, because no one (absolutely no one) is changing their positions, no one is buying the bull, and no one can even understand fully what he and the back patters are saying to get terribly mixed up along the way. So how can there be discord when no one understands enough of the spiritual-babble to buy it?
(And that's exactly why I really meant it when I said you see it one way, I see it another, and maybe we're both seeing a mirage. We aren't seeing it the same way, so there really is a good chance neither one of us is seeing the reality. Mirages really do look like water on dry land. It's not an hallucination, but it could be our eyes playing tricks, or it really could be a puddle.)
Second, you once said that one of your kids was having a major meltdown in a store as a toddler, so you did the same thing (plopping on the floor -- I don't recall you saying you did the scream and shout part), which got his attention so you could correct.
If I'm not mistaken, (and I could be again), isn't he a teenager now? If he has an "in your face, gotta have it my way" explosion in a store now, would you do the same thing? And, if you did, do you think it would be as effective as the first time you did that?
The reason I ask is because the guy we're not mentioning by name is your age, but this seems like you're treating him as a kid. I get why. (I really really do.) BUT I don't think treating him that way will get him to do anything thinking at all, so what's the purpose?
And, just so you know, yeah. I've told him I'm ignoring him from now on, so it's not the decision to ignore him. (He's not listening, so why keep talking? Right?) It's all a matter of perspective. The way I see it is he caused no discord since he and the back-patters are unto themselves, and he's not listening, so why go through all this?
I'm not worried about him right now. I'm worried about you. What was the purpose of this for you?
