Once again, stupidity knows no bounds. It is indiscriminate and appears to be naturally occuring, specifically observed among the human species. Whether this is an act of Providence or a probability that is decidedly random by nature of distribution, it is absolutely uniform in whatever subgrouping of the human population conjured and put forth. This is why it is independent of any characteristic of that person.
Now whether this sort of stupidity is redeemable is difficult to answer and prescribe. We should all recognize that change is possible and that we are in constant flux of change from either being profoundly misguided, or from having undeveloped maturity and conscious. Redemption in most cases is possible.
