How did the denmark vesey plot contribute to increased sectionalism

slave codes that had been developed as a result of the stono rebellion during colonial times were strengthened to better protect white society

"Being, after some time of entertainment and gifts, dismissed, a while after he came again, and 5 more with him, and they brought again all the tools that were stolen away before, and made way for the coming of their great Sachem, called Massasoyt; who, about 4 or 5 days after, came with the chief of his friends and other attendance, with the aforesaid Squanto." I would say this sentence shows the Indians wanted to make peace by returning the stolen tools and bringing their chief to meet (the white Americans?) and having entertainment and gifts as well for the (white?) guests.
