What was Brown interested in other than an end to slavery?
That's just disingenuous argumentation. The fact is, slavery was legal, and what John Brown did about it, wasn't.
No arguement there. Slavery was legal and Brown's actions weren't. But I believe that the original topic was about all the clauses in the Mississippi Declaration of the Causes of Secession which didn't concern fears about the fate of slavery. I'm still not finding any.
Was not the topic of this column, issues concerning a billboard?
