Therein lies the crux of the whole situation, and what Rajesh appears to be blinkered from. Why would angular momentum originate at the ergosphere? It is called frame dragging [Lense Thirring effect] which specifically and by definition is caused by a rotating mass. So where is this mysterious rotating mass? Then we predict the ring singularity. Do we have a ring singularity if it wasn't spinning? Again it is totally reasonable for someone without an agenda, to assign angular momentum to a Kerr metric BH [all of it] as well as a rotating mass in whatever condition it exists. Again, despite being written off by Rajesh as inconsequential, when these professors are asked about the ring singularity, if by a stretch of the Imagination it was not/did not spin, then obviously that is what they would say. To deny that is to deny fact due to a burdensome agenda, which includes from day 1, his belief that BH's do not exist, and appears to be trying to create some sort of manufactured paradox to support that ideology.
