do explain
Explain the difference between good/bad verses right/wrong? Surely you jest. But for the mentally challenged, I'll explain. Good/bad are subjective where right/wrong are linked with moral rule
Morality is subjective and 'right' and 'wrong', in common usage such as your own speech, as synonyms for moral and immoral.
and legalities in regards to slavery
Law is based upon morals and interest. Laws change and vary. To say it is wrong for me to enslave a man and right for you to enslave him, based merely on the idea that I put into effect a law allowing myself to enslave him, is disingenuous at best.
In Africa and other parts of the world, slavery was morally accepted and perfectly legal.
Ah, so it can be considered moral r immoral by different persons. We're back to them being subjective terms, just as you said 'good' and 'bad' are. If you believe slavery is wrong/immoral, then you must oppose it wherever it occurs and regardless of who is doing the enslaving. That's what it means to have principles.
Yet you continue to defend slavery as right and moral. Typical of your ilk; noone expected anything else of you. Now, go back to your little Klan rally and come back when you have a clue.
You are dismissed, racist, illiterate moron.
