because I am a Christian, not a tribal idol-worshipping heathen, it'll be OK.
That's a bold statement, considering you are standing IN tribal land...oh and, Christianity has killed more people than Indians. Albeit, I would probably concur that we are better off with Christianity, as much as it pains me to state.
Are there not idols in Christianity?
Morality comes from knowing right from wrong (which may be the question). Simple as that.
