But I am a Jew (who has become atheist in beliefs, but cannot by any means stop being a Jew). So I was raised to distrust everything Christian. It is natural that I am scornful of Christian things.
This very idea of "Being saved by faith" leads people astray. They think they can do anything they want, as long as they put on a convincing show of "believing in" something.
But I know darn well that such things as the Ten Commandments were written by US JEWS, not G-d...
