One notable exception to this was Jeremiah Dixon, of the Mason-Dixon line. From Wikipedia:
> "Jeremiah Dixon, happening upon a slave driver mercilessly beating a poor black woman. 'Thou must not do that!' he shouted. 'You be damned! Mind your own business,' came the reply. 'If thou doesn't desist, I'll thrash thee!'
> Tall and powerful, Jeremiah seized the slave-driver's whip and gave him a soun thrashing. When he returned to Cockfield, the whip came too, and was one of the Quaker family's treasured possessions."
> Quakers are one of the three historic peace churches and therefore have taken seriously the call to loving enemies and the practice of non-violence.
