I am all for the law, and understand that others are not for it. But what is the meaning of arguing if it is constitutional or not? Israel doesn't have a constitution! so please point out which constitution it complies or violates. Otherwise you just sound like an uneducated idiot and makes me wonder the validity of the rest of the words coming out of your mouth or being printed on the web and paper.
