Understand, Black people did not get a vote in the drafting, adoption, or ratification of the Constitution in 1787. We did not get a vote in the drafting, adoption, or ratification of the Reconstruction Amendments. We did not consent, tacitly or otherwise, to this slave state. And we were systematically denied political power in this country until roughly 1964
This is why the Conservatives are pulling history books out of the schools - so no one will argue the need for Black voters to vote & hold political power.
