There is a big difference between economic slavery and chattel slavery.
One is immoral and has been made illegal in western nations, the other will never really go away and most be kept in balance if we wish to have liberty and capitalism. Conflating the two to make a political argument is a bit immoral in itself, but one can see how people get confused. Still, one can’t but help say “division aside, there are real non-divisive problems here, like the rampant child sex slavery problem that plagues our globe here in 2017“.
Do I care about the wealth gap, private prisons, and politics? Yes, but I know we don’t all agree there. However, we do all agree on the morality of chattel slavery and that is still real and a problem, so lets start there.
