It actually is true thought, that some supermassive blackholes have a density thats pretty close to that of water, and their event horizons are very very gentle

I think this is only the case if you consider the mass density to be uniform within the event horizon, which isn't true.

  Right, but I don't know how else to interpret what he's claiming. Singularity or no singularity, if there's an event horizon, there's a black hole.
