Some very intelligent people are at the same time horribly wrong in their world view. But they have had years of thought and study to obtain and back up that wrong thinking.
Many of these very same “smart” people also have the presumption that you are not truly “smart” unless you adopt the progressive attitudes, and move in lockstep with them as they change, sometimes swiftly and at great divergence with the previous rationalizations. (Orwellian doublethink!)
One need not go to Harvard to be truly intelligent, and in fact the indoctrination they undergo there is a DELIBERATE dumbing down of what would otherwise be a very high degree of creativity and logical thinking.
It would be great mischief indeed if a truly intelligent person made the mistake of enrolling in Harvard, or for that matter, the vast majority of institutions of “higher” learning here in the US.
