I read the article pretty fast, but what I seem to understand pretty much is we should understand one another, condemn our dark past, move on with loving one another, and find what we have in common with one another.
I like dialogues. I think it helps understand the position of the other better. But I do feel it's time to push the envelope just a little and address the things that divide us. I think many well-minded clergy that are involved in these dialogues are not polemical enough to cause a misrepresentation of the others' beliefs. I feel there needs to be an umph of a challenge while maintaining the love so to speak. I just hope that the challenge doesn't degenerate into past polemical jargon, which might be the risk, but I believe it's a risk worth taking.
