It's an odious, reprehensible argument, just like "It was not immoral to gas Jews in Auswitch." Some arguments should not be dignified and legitimized by a response.
Maybe you can't give a simple yes or no answer because you haven't figured it out yet.
Translation: I cannot offer any arguments so I'll just spew invective.
You really are pathetic, know that? Something that you claim is as obviously wrong as slavery you cannot come up with a single argument against it.
That's pretty funny coming from the guy who can't say that slavery is bad.
Next topic, Rabbi is going to ask why do people dis the Holocaust?
Because, hey, once you can't say slavery is bad, is it really fair to criticize genocide?
Wow you are getting even more pathetic. You cannot make the case so you just repeat yourself over and over.
Hang it up, turkey.
