Buzz,
We agree on that part for sure and I think most of what you posted will turn out to be factual so far as we now know. I have always had a problem with there being two entrances into a black hole as it just seemed strange to me and that was why I tried to use the tornado description to explain how I sort of envisioned one.
Edit: I am using the tornado just as an example of how I would envision a black hole looking if you could stand off and see the thing from top to bottom. The end of the tornado funnel would be the singularity, except in a tornado if you were at that end you would likely be pulled up and into the funnel and not down into it like in a black hole.
