Practical advice to both sides: don't assume that the other person is an evil mutant. Practice releasing againstness. Model the other person in enough detail that you can understand why they thought what they just said was a reasonable thing to say. I think that's a good place to start.
It's a good advice, but not at all what I was asking. Feel free to post your advice on the site, I don't read it or participate, only got linked to it.
If it's worth saying, but not worth its own post, even in Discussion, it goes here.
