A Japanese Professor emeritus (which is who he is) might find the recent behaviour on this site rather demeaning, I'd be worried you may have lost his support. I work not far below that level and the morlocks here would dearly like to have a go at me recently. Robust debate is one thing, what's been going on here another, and he may have walked away: someone he values should contact him at his university and apologise - after sorting out the mess here.
