No other group since 1600 was uprooted grim their homeland in the millions, no other group had their slavery justified on the basis of race, no other group, even after being freed was denied participation in society, restricted and denigrated because of their race.
The only event that comes close is the holocaust, and that lasted only five years. Black slavery lasted three hundred years.
“no other group had their slavery justified on the basis of race”
You forgot No other group was sold into slavery by their
own race. African slaves were sold to buyers by African
masters.
You mean blacks enslaved by whites lasted 300 years.
