If I recall correctly the original incident came to fruition through a Masonic author from the Phylaxis Society attempting to give a speech in regards to the legitimacy of Prince Hall Masons to the Dallas chapter of The Philalethes Society. The Grand Master of Texas ordered him not to let the Prince Hall Mason speak. So the Philalethes Chapter President closed the meeting and all went home. Shortly thereafter the Philalethes Society was banned from the state of Texas and to this day it remains banned.
As to whether Brother King was loose cannon remains to be seen:
As Brother Allen E. Roberts states in “The Seekers of truth”:
The Philalethes Society Seekers of Truth:
Petty tyranny gave birth to The Philalethes Society," I wrote in 1988. "Some Masonic leaders," I continued, 'dressed in a little brief authority,' had attempted to inhibit the spread of truth. They had attacked, in many cases successfully, the publishing of the written word. They had endeavored to warp the minds of the greatest intellects in Freemasonry."
