Notice that the God of the Bible only destroys those who are against Him.
So it's "worship me or I kill you and you'll burn in hell!"
Isn't that exactly like the abusive husband that tells his wife he'll kill her if she leaves (is against) him?
We don't put up with that kind of behavior in society, why would we put up with it in religion? Give a strong NO! to your god and go to a shelter (aka education).
Luckily, more and more people are doing that in record numbers every day.
Furthermore, with the flood he destroyed almost everyone, so he either thought everyone was against him wich is stupid because probably 90% of people didnt even know he existed (if he did) or he just likes to kill people.
...or HE DOESNT EXIST.
