I wasn't expressing any hostility. Why did you think so?

If I learn something from you, then you congratulate me for realizing what you had known, then I would be denying my gratitude by presuming you were gloating.

I had to deal with 5 pages of trolling by your colleague (well he claims some affiliation to you). I am entitled to acknowledge your realization. There is no animosity intended. You are being rational and so am I. I was just relieved the trolling had come to an end finally.

Carry on. We both have work to do.
