I haven't the foggiest idea what part of being descended from people who approved of slavery, abuse, oppression and cruelty ranks as something today's southerners hold dear.
What part of being descended from people who enshrined official support/sanction of the institution of slavery within it's very Constitution do Americans hold dear? Ever hear of Article IV, Section 2, Clause 3 of the United States Constitution? Also known as the Fugitive Slave Clause. Ever hear of the Fugitive Slave Acts of 1793 and 1850? Yes, Virginia .... slavery was entirely legal in the United States up until after the civil war ... and approved of by many in the North.
What part of being descended from people who sold their own people into slavery do blacks hold dear?
What part of being descended from yankee ship owners & merchants who became wealthy via the trans-Atlantic slave trade do northerners hold dear?
What part of being descended from people who engaged in indentured-servitude to northerners hold dear?
What part of being descended from northern factory owners who engaged in child labor do northerners hold dear?
What part of being descended from people who engaged in torture and who massacred white pioneers despite their tribes having made treaties with them do Native Americans hold dear?
What part of being descended from people who engaged in witch trials, burnings, and hangings do people hold dear?
What part of being descended from people who engaged in the rape of Nanking; enslaved Korean men into forced labor; and enslaved Korean women into prostitution do Japanese-Americans hold dear?
What part of being being descended from people (Spanish/Aztecs/Mayas) who engaged in slavery do Mexican-American's hold dear?
New York State did not passed it's first gradual
abolition law in 1799 and did not finally abolish slavery until 1827 (New York slave owners just sold them over the river into New Jersey ... how convenient.)
Massachusetts was the center for the trans-Atlantic slave trade. Slavery was common in 18th century Mass.
There were over 11,000 slaves in New Jersey in 1799. 6.2% of the population. A gradual abolition law did not come about until 1804 and mostly just converted them to indentured servants for life. Full abolition did not come about till 1846 ... but even that only converted them to "apprentices" for their masters.
There's more to the South than just slavery, 'WordSlinger' ... and slavery is not what the flag represents nor is the idea of it "something Southerners today hold dear"
as you so incorrectly assume. The so-called "civil war" was about secession & the limits of State sovereignty. Slavery was just the economic trigger event. Not a lot of people in the northern States previously had much of a problem with the Southern states engaging in slavery ... they knew the benefited from it. Lincoln himself said if he could preserve the Union without freeing one slave he would do so ... yet he is revered and no one is talking about tearing his statue down?
No slight to African-Americans .... but, sorry, the civil-war was not just all about you.
