I don’t think anyone alive today had that happen.
Many of them died at least a hundred years ago. And slavery itself, it was abolished 150 years ago, in a much earlier period in American history.
I agree with your sentiments, but religious and ethical groups, and eventually Abe Lincoln and others of a like mind, abolished it—by our own constitution that was already in place. God made all persons equal— a man is a man, and if the U.S. constitution applies for the liberty and rights of one ethnicity, it must include all.
But your point is taken. The democratic party remains, It started the Trail of Tears, expelling the Cherokee nation from their homeland even though the Republicans thought their nation in the Tennessee- North Carolina mountains, could coexist—as with other Indian nations. And Slavery the Dems clung to— demanding segregation well into the 1960s. But it changed its position on these matters during the Eisenhower or Kennedy administration and stands up for your rights nowadays. As long as you stand for their agenda in political matters.
