That is a fairly good post ratbastid.

Just a couple of points:

"The singularity is, like any black hole, infinitely small. But it's also SMALL--its mass is that of the two subatomic particles that created it. So it's not the massiveness that makes it a black hole like in cosmological black holes, it's the density." Actually, the mass is greater than that because the particles had kinetic energy (from their velocity) which also gets turned into mass.
"The second is that it's now emitting Hawking radiation. This is the safety valve built into the LHC (and unlike other gross speculations, rank assertions, and wild-ass guesses I'm making here, this paragraph is 100% true). Hawking radiation is emitted by black holes of any size, and since it causes the black hole to lose mass, it theoretically should have any micro black holes evaporate nearly as soon as they're created." Hawking Radiation as well as many other theories that relate to the decay of blackholes is still theoretical and debated. But I mean come'on, it's Stephen fuckin' Hawking.
"But eventually a time will come when its event horizon is the size of a golf ball, and it's eating a golf-ball sized channel through the earth with every pass, then the size of a baseball, eating a baseball-sized channel, then of a basketball, eating a basketball-sized channel, until it's the size of a car, then a house." Doing a quick calculation on a blackhole's Schwartzchild radius, the event horizon's diameter doesn't reach an inch (0.70" or 18mm). Granted I can't figure out if I have to take into account the potential energy of the engulfed mass. An argument against it is that the blackhole is moving at speeds far less than light, and the potential energy of the mass inside is not comparable to high Lorentz contractions (gamma constant effects).
"strong monopolar magnetic field" Monopole magnets are impossible even with blackholes. A blackhole does not retain charge or magnetic properties of the mass engulfed inside it. Plus, relativity prevents the existence of monopole magnets (I don't know how, I just remember a rant of a professor about how unrealistic science fiction movies and games are becoming).
