Animal Slavery

[Angrboda]

False dichotomy. There are other options, such as it being in our self-interest as a biological species,

Yes, slaves are in the self-interest of the slave owner. Does this justify human slavery? If not, why does it justify animal slavery?

Whether it is adequate justification or not is not the point. You are attempting to mount an argument about god on an invalid premise, the aforementioned false dichotomy. This doesn't make it any less a false dichotomy and therefore your conclusions about god based on the dichotomy are non sequiturs.

If, as your argument goes, it is in our interest as a biological species to maximize the utility of non-human resources to increase our odds of survival, it does not follow that god has an equally rational basis for his behavior because he is not a biological being whose interest is defined by his biological nature.

So, nice try circling back to your original unsupported premise about animal "slavery" being immoral, but you failed.
