Why is this a gender issue? Is it OK for women to spit on her? It has nothing to do with girly men and the mentally twisted. Spitting on someone is a widely-practiced gesture of contempt around the globe and through history.
It is even in the Bible
Yeshua our kinsman-redeemer was subjected to the humiliation of being beaten and spat upon by those who mockingly said to him "prophesy to us Messiah, who hit you?" The people were awaiting a Messiah whom they thought would redeem them from Roman oppression, not from their slavery to sin. He was treated with the gesture of contempt reserved for one who was unwilling to redeem.(Ph. 2:7-8).
As the young folks say, "what--ever." In today's world, spitting is for losers, geeks, wusses, dweebs, and latent homosexuals. If I'd seen this guy do what he did then run away like a girl, I'd have tripped him and held him until the cops came.
