You’re the one who started asking stupid questions instead of just arguing your position.
You accused others of making excuses for slavery. That was not so of the others. They — joined by I — were explaining that there are many forms of slavery, and some are not so bad. At first, it seemed that you were a black-white thinker, incapable of seeing the middle, only seeing the extremes.
Slavery is a degraded condition for a human to be in, and owning slaves often little better or even worse. It seemed that being you were in that black-white and nothing in-between mode some headway might be made in the discussion by discovering what it was that you considered “slavery”. You answered, after some prodding, “involuntary servitude”.
But in answering the questions about few detailed circumstances of what might be called slavery it became clear that you have one ax to grind, and that ain’t about slavery. In fact, it appears you do not really care about the circumstances of fellow humans currently subjected to slavery — perhaps because it is slavery hiding under another name, in a culture you are positive or neutral about.
The ax you hotly wield in hatred is that of Jew hatred (or hatred of the long established legal and religious traditions of Jews). That grudge — hatred, jealousy, envy or whatever combination of same — blinds you.
Grow up.
