Of course, Chris. The Good Lord himself had his detractors, it would be very surprising if Dan didn't have more than a few. But the same calculation of % out of all those who were there applies on both sides of the ledger. And balancing those who don't like to say anything negative are those who would very much have liked to say something negative about Dan.
But (all together now) IT'S NOT ABOUT DAN. It's about the overwhelming acceptance of the skills he's been kind enough to share among experienced aikidoka. That's the phenomenon that needs explaining.
