Being raised in the same family does not necessarily mean you were raised in the same way. Many parents treat each differently and respond to each child differently. Poor personalities, I find, tend to have been the pet of a mother with lousy parenting skills, while the siblings who turn out all right will have been left largely to their own devices by this parent.

Just because he appears to read voraciously doesn’t mean he understands all he reads. Most of his ‘genetics’ arguments, for instance are a load of balls. I am sure that extrapolation of this to his grasp of something as abstruse as Nietzsche (himself not the full set of lights) can be safely applied.

Children adopted from birth, unless there are serious genetic personality problems, will turn out more like their adoptive parents than their biological parents (except in appearance, of course).

Not really, but would definitely make voters think twice at the next election.

By the way imagine how this boy is being brought up with a sense of entitlement and self-importance.
