him developing a hatred of the cotton producers as a consequence of bitter disappointment in his efforts to make a living in the wool business.
John Brown’s life was devoted to anti slave activity. His father’s home was a stop on the underground railway. The first house John Brown built in 1820 had a safe room for runaways. While living in Plainfield Mass, he joint the only church run by abolitionists, He help turn that town into one of the safest stops on the underground railway. No slave that made to Plainfield was ever returned to slavery. He was in the tanning business for 15 years before getting into wool He learned the tanning trade from his father, (Jesse Grant, U.S. Grants father, learned tanning as a Brown apprentice) He was in the wool business for about 3 years.
Brown was an abolitionist from his youngest days. I think it is a far reach to say failure in the wool business motivated John Brown into abolitionism. He was there many years before he had anything to do with wool.
You make a good case.
