Interestingly enough, I read that ISIS wants to bomb Mecca for reasons that sound like they have judged pilgrims to be guilty of idolatry.
Yes, very much so, to the effect that as of this moment, the Saudis are building a 600 mile 10 meter high fence (just like the Israelis) to prevent ISIS from over running the country. In fact, ISIS, who the Saudis had once supported consider the whoring Wahabis unworthy as ‘Guardian of the holy Places’ and have threatened to exile, if not kill them from Saudi Arabia.
The same thing happened with osama Bein Laden. He wanted the Saudis out because they allowed the infidel american armed forces stationed there during the first Iraqi War. Jewish soldiers, too.
