Lisle said:
"Yes, the type of slavery advocated in Scripture (helping an irresponsible person get out of debt by paying all his debt and training him to become financially responsible) is morally right"
Lisle seems to be ignoring the fact that people get into debt for many other reasons beside their own "irresponsibility" (ie. medical debt)...
Other problems with your view, Lisle, as brought up by a smarter person than me:
1) That isn't the only type of slavery in the Bible. That's the type of slavery you could use for other Jews. When applied to people captured in war or gentiles it was a form of oppression, not a repayment of debt. Foreign slaves were slaves for life.
2) Repaying a debt is one thing. Being a slave is quite another. You can't beat someone to repay a debt. You can beat a slave so long as they don't die in a couple days from the beating. You can make a slave do things that violate their rights, whereas someone who's doing community service work or doing chores for someone to repay a debt still has the right to say "no" if they're asked to do something that violates their rights. A slave can be raped and beaten and they're expected to accept it. A vandal who gets caught defacing a business can sue the business and get the owner arrested if he's beaten and/or sexually violated.
3) Owning a person is never right. Even for a short time. Paying back a debt and doing thing you don't like? Fine. Being forced to do your master's bidding, whatever it is? No. A person needs autonomy, even if they are in debt to you.

"You again demonstrate the truth of Christianity by the very questions you ask."
How does the debate about moral absolutism prove that Yahweh created a garden with a talking snake in it, flooded the world, impregnated a virgin with himself, became a carpenter, died, and came back to life?
I'd LOVE to see the train of logic that leads from A to B on that one. What's to stop any other religion from making the same claim? Try and answer that without circular reasoning and begging the question.
If we actually got our morality from your holy book, Lisle, then slavery would still be morally "right", as would killing witches, those who work on the sabbath, etc...
Our morality does not hinge in any way upon the christian "god". In many cases, they diverge.

Edit: I forgot that I had responded to Lisle on that topic once before.
