I think the phrasing is what does her in. There's nothing inherently wrong with what she's saying, that's how they get you. Conflict resolution is an important skill and it can be learned, or not. But the concepts she's presenting here, that one party can just "teach" the other why their current thinking is flawed and how to fix it, it's dangerous if mishandled by a particular kind of person. Her phrasing heavily implies this relationship is not equal, at best.

I've know manipulators, a lot better than I wish I did. The way she's worded her post carries a lot of unfortunate implications, hell I wouldn't even be surprised if she didn't even realize it.. but it's there and it's obvious.
