“...perplexed...”
It’s not that hard to understand. There are several different organizations of the Klan. Obviously, the alledged rally was being proposed by a rival Klan to the Memphis chapter of United Klans.
Having never had any association with the Klan or even knowing any klan members, I just assumed that they would stand with other fellow klan members before standing with blakcks. Thus my confusion. I have since learned that klans are nothing more than social groups now. Who knew, certainly not me.
