Hmmmm. I don't know exactly how one would define "arbitrary," I guess. I think that "arbitrary" in this case means anything the poster disagrees with. I thought I had good, precedented reason. We don't allow personal attacks, and the thread title was an open invitation to personal attacks - and I'm grateful that people did not respond to the invitation. The original title remains in the the earlier messages.
And yeah, if this thread turns to a string of personal attacks, I will close it. That's my job, arbitrary or not. So get the bee out of your bonnet.
