i have to say actually even in egypt, and in sinai in particular as we had a lot of israeli's coming in after finishing national service or whilst on leave and they could be incredibly difficult tourists to deal with, whilst there was oh god we've got israeli's to take out today get ready for it (arrogance, beligerence, treating you like you were a twat because you were female and non israeli and who does SHE think she's telling what to do - and when you're taking overly confident people diving you really do need to be able to tell them what to do and have them listen) it was never about jews. i never heard anyone say 'bloody jews' today or jewish people are so... (insert insult).
there was no mention of religion, it was based on nationality and based, for most people, in an awareness that it wasn't all israelis but arrogant puffed up young men who were in a particular mentality state after being in the military for a while.
the koran tells muslim that we are all people of the book, it does say that each of the preceding people fucked it up somewhat re: the jews lending money and various incursions on the law and the christians are seen as perverting monotheism by making a god out of a prophet. so the religion teaches that those preceding it made mistakes but it doesn't tell them to hate but to see as being under the same broad umbrella.
where you see supposedly 'muslim' extremism imo, it is, as always when religion is hijacked, political extremism. religion is a handy vehicle because someone is (apologies) already brainwashed to a certain degree and that brainworm can be exploited to brainwash further and that belief be facilitated to politically brainwash someone in such a way as to attach to something seen as sacred. presumably the same brain worm is exploited by israeli leaders when manipulating people and programming fear and loathing of an enemy that allows for inhumane behaviour to be committed.
again it is power and corruption that is the enemy. it's unfortunate that the corrupt and powerful have always abused religion as a way of justifying themselves, hiding the real strings of power and making people fight for what they believe is holy or just when it is in fact just power play and politics again and again and again.
that's all my opinion obviously. i just really don't believe this is about religion. it's a well used misdirect that we all need to get past and stop being manipulated by.
