Why does the religious right defend the genocide of Noah's flood?

 I was listening to conservative talk radio. The host is technically  of conservative Judaism, though his beliefs are very much in line with Orthodox Judaism. But, he defends the so called Noah's flood as strongly as any fundamentalist Christian. First of all, this flood never happened. It is a myth. It is possible it is based on some big regional flood and the mythology of it grew from that event.

No one can be for sure, but clearly the history of the bible, especially the Old Testament, is not history but mythology. Anyway, this host defended the flood. The killing of innocent men, women, children and all the countless animals. He did not deny that there were probably other good men, in this story, but that Noah was supposedly the best. 

 He stated the killing of children was O.K., because without adults, how could they survive? Lastly he said the killing of all the animals was fine because animals were made for humans and they are to do with what we want. O.K., this is his premise, now my rebuttal.

First of all, this line of thinking shows the absolute lack of rights and freedom to the religious fundamentalist mind, that we human beings have separate from this god. We are the playthings of this god. He can torture us if he wants. He can kill us if he wants. He can commit genocide at his whim.  He kills and commands killing, many times in the bible. Heck, even for a census by King David.

 See, the bible isn't about rights of course, it is about the dictatorship of this god. Now, isn't this deity all powerful and all knowing, at least according to these theocratic types? Yes, so he knew before he even created human beings that he would kill them in a flood because they supposedly weren't moral enough. Wow. But, this god, who designed and created these humans is disappointed at the people?
The people who he knew before the creation event itself? If a scientist creates artificial intelligence and he knows completely that these beings will be bad in some way, is it not his fault? Would he right to kill them for his own mistake? That is what the bible says about people. We are his playthings.

 The host had stated it is fine for children to die, but why can't an all powerful being ensure that children survive post-Flood? Why so little concern for animals? Does that mean humans can use them for anything they want? Are animal welfare and animal cruelty laws than unbiblical? 

 If someone will believe the rationale of Noah's flood, what will stop him or her from committing genocide in the name of this god? Well, nothing really. Of course genocide in the name of a god is nothing new. Violence in Europe was commonly done in the name of religion, before the Enlightenment (which gave birth to our nation) curbed its' worst excesses.  

So, whenever someone talks about absolute religious morality, just remember, these same people think it is perfectly fine for their god to take your life at any time. This god commands we follow the letter of the bible, including not eating shellfish, but he can kill at will. The only good thing I can say about this god, is that at least he doesn't exist.
 Oh by the way, this host also said that all leftwing ideas sound nice but they don't pan out and fail. I guess he neer heard of leftwing ideas such as democracy, the right of women to vote and the end of slavery. All by leftwingers, be they secular or religious.
