Hi Professor...Nice answer. The other points being argued on and denied in this thread if you have the time are as follows.  A charged BH [although a rarity] will in time lose that charge by attracting opposite charge.  A BH can also over time lose its angular momentum.  Within a BH's EH the effects of tidal gravity which move towards infinity as we approach the singularity, also spaghetiffies any body/mass falling into the BH, eventually overcoming the strong nuclear force, so reducing the matter to its most basic fundamentals.
