well, i personally think it's very silly to blame the jews for jesus's death, seeing as it was meant to happen right? if god had sent jesus to be a sacrifice or whatever, it's hardly fair that jewish people get the rap for technically doing what they were meant to do...
all religions have huge weaknesses, even christianity, with the enforced catholic dogma and segregation that jesus himself detested (ala the veil being broken at crucifiction, etc.), which the jews also slipped into during the roman era. and well, islam has had some pretty bad things done in it's name too.
the fact of the matter is, when someone is controlled by their religion so tightly that their faith is not their own, but the religion's that they so willingly follow, religion is a bad thing. people forget what it's all about and use it as an instrument of power.
if you've got faith in god, great, but let it be your own, and never persecute those with their own faith too. it's hardly 'what jesus would do'.
