I don't think a black hole is a singularity as described in wikipedia.

My speculation on a singularity,
Consider the singularity of a black hole, to get there you must travel a vortex that will get you moving faster than "visible" light, oh, and the path gets narrower like a funnel, so you will burst down to the size of the funnel mouth. Then the flow of particles(tiny but with immense force)......

As they all formed in the same direction due to the vortex like with magnetism their force would be aligned.
So they are deposited onto the core which rotates on the same 2d plane as the vortex but in the opposite direction, the mass build up creates greater pressure in a pole axis that runs through the core perpendicular to rotational plane. The particles being compressed eventually burst again and that is the high energy flares on the poles.
