Does someone know of a religious basis for this? (other than shoes being forbidden in mosques)
I am not asking for any moral judgement about shoe-throwing, or about the people receiving shoes in the examples in the links.
Thanks in advance.
Sidenote : This question is not meant to be a critic. Personally, I find throwing shoes during disagreements a quite acceptable "habit". Not only does a shoe do limited harm, but it also gives the time to the thrower to calm down and think about his action while he fetches his shoes back or goes home bare-foot.
