@Olivier5,
It's one thing to say, don't eat that, it's an abomination.
It's another thing to kill the person for doing so.
Many of the laws suggest a person who breaks them should be dealt with via stoning until dead.
It's like the guy who was put to death for picking up firewood on the sabbath.
They come up with a rational based on something that is completely irrational. Just because it states in your ancient story that a god rested on a particular day why would it suggest that everyone else must also do so or they should be murdered?
A really caring god, would be like, woah! hold on a second. Yeah I rested but I don't expect you to, by all means if you need firewood on saturday, go out and get firewood. I don't want you to freeze or starve just to appeal to me.
Ye this is not what people do. They say their god commands that you be put to death. It's absurd.
