As an example of human stupidity I have an old colleague who is exceptionally intelligent and capable and closely connected with
eggheads winners.(superbrainy people, usually the middle/upper middle classes)
He doesn't like Turkey, so on xmas day his family were not allowed to eat turkey.
This is like banning turkey from your home at thanksgiving, because
you don't like turkey
He didn't care that others liked turkey, even members of his own family were ignored because in his head he is the son of god on earth and it's all about him and what he wants and nothing else matters including his own family
This mental disease is especially prevalent in the middle classes, they call it
hubris and I'm afraid it's a genetic trait that will contribute heavily to the human race lurching from one millennia to the next
The other trait is apathy, which I'm sure you are well aware of and contributes heavily to compounding various problems
I did eventually suggest to him that perhaps his family could have turkey while he had a curry or whatever, since it
was Christmas day and xmas day
is a family day
This "brilliant and unforeseen" solution has since been adopted by him, a member of the top 3% intelligentsia in British society, a man who could get a degree in advanced astrophysics... but couldn't get a school leaving certificate in common bluddy sense
