Not un-Masonic, but authorized under the Digest. I wish some few folks had taken a little more time to whisper good council, but that was a problem of the times. The records are freely available there in the 2012 & 2013 Proceedings, and the expulsions were upheld by the Grand Lodge at the following convocations.
Scimitar Shrine is just a few minutes down the road from my lodge, and Sahara is just 45 minutes south from here. I am familiar with most of the GL officers involved, as well as most of the Shriners. I am not a Shriner, nor does it look like I will have an opportunity to be, but having observed the guys left over there at Scimitar for the past two years, as well as the ongoing fuss, I can't really think of anything they do that would make me want to become a Shriner any more. What has gotten out over the web has been pretty much a one-sided story, and somewhat incomplete.
We've had some pretty good shifts in the ARGL line in the past year, and things are looking up. But the local Shriners, with the backing of their imperial staff, have dug themselves into a pretty deep hole, and are still digging.
