Quote:why Catholics use the crucifix instead of the cross in the churches?
Catholics believe Jesus 'suffered and died' on the cross. A cross is a symbol, a crucifix is a reminder.
I hardly think it's fair to blame the actions of one man on an entire belief system. I was raised a catholic, the first time I heard the term - "Jesus Killers" I was long past practicing anymore. The local university newspaper ran a comic strip featuring the idea. I think micah has given you an accurate answer to your question of how 'most' christians feel. There are fanatical crack-pots in every religion. Osama rings a bell, but I don't think he speaks for all muslims.
All major religious beliefs have similar tenets - Love thy neighbour... unfortunately, a few of them can't see beyond those of like mind. Hardly a surprise given the long history of religious intolerance this world has seen.
