Classic BS. Slaveholders from Missouri (my home state) initiated the use of violence and mob rule in an attempt to control KS.
These methods were retaliated upon them, they lost the ensuing fight, and then they retreated to the position that they had been unjustly attacked without provocation.
Come to think of it, that's almost exactly what happened in the larger WBTS.
I pick an unnecessary fight. I lose, due to severely underestimating my opponent, and spend the next few centuries portraying myself as the victim of unprovoked aggression.
Nice work, if you can get it.
Well, now...one of my ancestors rode with Quantrill, and he wasn't a slaveowner at all......from St. Joseph, Missouri
