“This is the level of discomfort we experience when someone outstretches a hand at us.”
If someone offering you a hand to shake distresses you as much as having your genitals groped, then you need psychiatric help.
I was using a sarcastic extreme. Westerners accept the idea that many Asians are grossed out when others offer their left hand, or even seeing people eat with their left hand.
So why should a refusal to shake hands be upsetting?
