Many on the left try to claim Frederick Douglass as their own. In the details, there's not a shred of Douglass they could claim.
Let us not forget that Frederick Douglass was a Preacher. That's how he got so good at speaking. He did so every Sunday morning speaking about The Lord.
I would be very interested in hearing what sort of argument he came up with to claim that Article IV, Section 2 (The fugitive slave clause of the US Constitution) was "anti-slavery."
