Bill O'Reilly has several issues regarding the Bible.
The most obvious one is how he thinks that somehow it becomes moral for someone to be killed for picking up sticks on the wrong day of the week, as long as its 'God' doing the killings.
Firstly he accepts that there are a lot of laws about slavery in the old testiment (Judeo-Christian), but then goes on to say that this Judeo-Christian philosophy is what the US constitution and declaration of independance was built around.
