leroy said:Maybe regulating slavery would produce less evil than forbidding it
Utterly stupid.
Slavery is evil, banning an evil cannot produce more evil than evil itself.
You are condoning slavery.
leroy said:Maybe slavery had a different connotation in the past
Yes, it was something you can do legally - i.e. OWN a human being, whereas today we are more moral.
You are condoning slavery.
leroy said:Maybe slaves where not innocent humans, but rather people that deserve a punishment (criminals)
So we meet criminality by perpetrating evil on them?
You are condoning slavery.
leroy said:Maybe those particular verses (or books) are not inspired
And then maybe none of the Bible is inspired.
leroy said:but granted Christians can provide an ultimate and infallible explanation for this problem, all we have are unsupported hypotheses
They're not hypotheses, they are evasions that result in condoning slavery.
