In general, I agree. People tend to use religion (or political ideology or science or whatever else they see as authoritative) to justify whatever it is they wanted to do in the first place. (Even if a neutral reading of the original religion/political theory/science might lead you to expect the opposite behavior.) That said, I do think that certain interpretations of religion can have negative or positive influences on the behavior and attitudes of the believing populace. Therefore, I have adopted the "by their fruits you shall know them" outlook: If your belief in Christianity/Islam/Buddhism/Hinduism/Wicca/Secular Humanism/whatever leads you to be kinder, humbler, happier, more generous and peaceful, and so on, then I say hoorah for Jesus/Allah/Buddha/Ganesh/Mother Goddess/humanity/whatever. If said belief leads you to be an arrogant ******* who hurts others or a miserable person who hurts yourself, then I say find yourself a new belief system.
