What about 'I must act like this because it is in the bible'? Or whatever religious book you have.Ive never heard anywhere during any of my time here on this earth of any religion that promotes an idea of anything less than self responsibility for ones actions.
I kill gays because they are an abomination in the eyes of god. I blow up planes because my god tells me to. I kill women if they do not wear the clothes (I think) my book says they should.
Do these people feel responsible for their actions? No, their excuse is that it is the will of god!
I am totally in agreement with you D that people have a right to have their religion in peace, and totally in agreement with T that it must be a private matter and must not impose on anyone else.
