As the saying goes where there is smoke there's fire....
At the very least I would say take a month off to gain some perspective...
After a month ask yourself if you miss it. If you do then go back. If you don't then move on to another system of Aikido if you like...
I have visited a few Birankai Place over the years and my experience is similar to Dan Hardin's....
Sometimes folks place personalities above principles and Aikido can be rife with that kind of perspective and that seems to be the case with your Dojo (Though you have to admit I only have your perspective.)
As for Misogi Again it appears to be personalities above principles
I prefer to share my practice(s) with folks who are somewhat modest and humble about their own practice.
