I do not know of any culture anywhere is which spitting on someone is not seen as a great insult. There is something about the act that is absolutely disgusting and so repulses people that it can arouse the most violent responses. So it comes as a bit of a surprise when very religious people adopt spitting on others as not merely an expression of disapproval but do so in an organized way, as if their religion prescribes it as a recommended course of action.
I am referring to the ultra-Orthodox Jewish community where it is not unheard of for large groups of believers to protest actions of others by surrounding them and spitting on them. I have written about such incidents before. And the stories keep coming of such appalling behavior, with the spitting seemingly always done by men, and women and young girls usually being at the receiving end, even if they too are Orthodox (see here, here, here, and here).
The reasoning of these spitters seems to be that the mere sight of bare female skin even on the arms is enough to provoke mad desire in these supposedly very religious men who would then be tempted away from thoughts of their god. Hence they have to punish those who tempt them with impure thoughts. Why women and girls should be the ones who are punished when it is the men who get the lustful thoughts and should be the ones who need to be taught to control them is never explained.
But since this seems to be a form of action that is approved by the religious authorities, the question arises as to where in their holy books they find justification for this widespread and disgusting practice of spitting as a means of showing disapproval.
