The idea that it would create a black hole isn't silly, it could well do. The silly bit is the thought that it would be dangerous if it did, given particle collisions at higher energies than the LHC happen regularly in the atmosphere and there is nothing particularly special about the LHC ones, bar the fact they are in a massive detector.
