You know, people like this do exist. I don't know if John is really one of them or just out to make a point or score a coup, but not being this sort of person, I have to wonder at the motivation:
* Were they once normal, or even sensitive boys whose fathers or role models foisted a hyper macho, desensitized attitude off on them?
* What does it feel like to be inside the head of someone who goes around perpetuating this kind of world view?
* Are they constantly worried that others will not think them manly or sexually driven enough?
* Or has it become a habit?
* OR is it a condition like ADHD (Attention Deficit Hyperactivity Disorder) that results from some chemical (testosterone?) imbalance?

It really does not seem to fit in with an advanced sort of global thinking.
