I know... and I apologize. It should be "odd for SOME Christians..." I completely forgot that Bro. TornadoApe falls outside that assumption sometimes.
Its that typical 80/20 rule.
Most(80%) Christians(or pick some other group) are sane, rational people who can have an in depth conversation about religion, beliefs and faith and not get offended or feel like they are being persecuted or something.
It the some(20%) that tends to cause the stereotypes that the rest are painted with.
That being said, You have to also remember Jesus spent his younger years in Egypt till he was what 14 or so. I'm sure he was exposed to the Egyptian religions and beliefs as well, who did have a code of ethics that if you read them sounds very familiar.
