This article (more helpful than the earlier one) seems to indicate that Mr. Parmley had his own personal agenda and he got shut down before he could implement it and possibly do harm to the MMP here in Texas. We at least were warned about troublesome provocateur's early on and possibly this is just one of them or perhaps he had visions of grandeur for political office somewhere. Who knows. The Texas MMP should work to put Mr. Parmley behind them and move on now.
I think Bill was doing a good job, from all I read, and that his resignation was a surprise to everyone. Something growing this fast, is bound to have some bumps and will require a lot of time and effort from many volunteers, just like the original Minutemen.
