Lisalias, I have not looked at the specific muslim website which you refer to, but I can imagine what may be on it (calling for destruction of Israel and west in genral etc?), and that if I did I too would be very scared.
BUT the Israel/palestinian conflict was not historiaclly about muslim extremism, the Palestinians were not orginally fundemental about Islam, they were on the whole, liberal and mostly secular muslims. (there also were many Christian Plaestinians) BUT they are becoming and have become, more extreme as the years of oppression goes on, hence the move of support from fatah to Hamas, allowing fundemental muslim groups such as Hamas, to use them as pawn against the West.
The teatment of the Palestinians by Israel gave many Arabs a reason to hate and distrust the US, the rise of muslim fundematlism may be a separate phenonmenon originally, but it gives justification and reason for its cause. It can 'use' the imjustice.
Surely that is obvious?
I was on the march on Saturady. I am a white middle class christian women, I was afraid that 70% of the protesors were muslim/arab and so so angry with the west and the US. 99% of them are reasonable poele british citizens who will only use poliical presssure to try to change what they feel is a huge injustce against thier poeple, but all it takes is for a tiny percetage to use this anger, for it to spill over into a joining fundementalist organistaion that hates the west and jews.
and Israels actions this week will I am afraid start that process for some. More exremism will be created, more terrorists. It is so self defeating.
So, if you really are scared by fundementalism (as am I) then you should be camapigning for a just settemant for the Palestinians. This will not stop the separate extremist groups, but it will stop them being able to use Palaestine and Israel as a justification and reason for their existence.
