Is slavery wrong, yes or no?
I'm waiting for your brilliant argument to persuade me.
Keep in mind that slavery is not the aberration. Freedom is. People have enslaved one another from pre-history to even today. So you would have to explain why it is "wrong" or unnatural or something to enslave someone.
Bet you can't do it.
How about a pretty simple one.
You wouldn't want it done to you or anyone you care about.
I wouldn't want to go to jail, nor would I want anyone I cared about to do so.
I guess that makes jailing criminals immoral too.
I wouldn't want to be drafted, nor would I want that to happen to anyone I cared about.
I guess that makes a draft immoral too.
I wouldn't want to be called for jury duty. Nor would I want anyone I cared about to be either.
I guess that makes jury duty immoral too.
Argument fail.
