How trivially easy would it have been for god to instruct the nation of Israel that no man should ever take another human as a possession?
The default cop out for JW about slavery is 'well everyone did it, changing that would be too much to ask, and God did made sure the slaves were treated properly'.
Well, God did not make sure the slaves were treated properly.
But more importantly, God had no problem issuing laws that (allegedly) went against what was customary.
Beards should not be cut, clothing should have a blue ribbon and fringes, can't eat blood, etc.
All laws that were different from what everyone else did. Some were specifically intended to set Israel apart from everyone else.
What better could God have done than setting Israel apart by forbidding slavery and discrimination of women?
Yet he chose to ignore these important topics and focused on food and clothes.
To me it seems this supposed moral guide has its priorities all wrong.
