There was slavery in New York in 1626 before the first auction. 1626-1827 is two centuries. You are also ignoring the "and discrimination" part of the statement that I made. New York had segregated neighborhoods until much later such as Stuyvesant Town which opened in 1947. NYC is also famous for its racially biased stop-and-frisk policy which lasted into the 21st century. Overall, it's pretty clear that my statement that there was "centuries of race based slavery and discrimination" is accurate even for New York.
Ahh, but they did not have institutionalized racial slavery before the auctions. Simply having slaves is not enough, as US slavery was based on the European peasantry model which has no racial component and it was only after massive influx of African slaves that the connection became so strong.
Also, segregation spread from the South after the Civil War so there was a significant gap from the end of NY slavery to the start of Radical segregation which means it was not a continuous period.
Remember the Civil War ended in 1865 slavery absolutely ended in NY in 1827, but was almost non existent at that time long having been phased out.
From 1821 until adoption of the 14th amendment in 1868 New York required black men to own property to vote but did not require white men to own property to vote. There are many other examples of discrimination that could be found, but your entire position is frankly too absurd to bother arguing against any further. The idea that there were not at least two centuries of time in which there was some form of race based slavery or discrimination in New York is preposterous.
I am not arguing that there was zero racial discrimination, we still have forms of racial discrimination built into the law today.
However, at the time women where not allowed to vote at all. Thus it was not pure racial discrimination.
Just for perspective North Carolina and New York did allow freed blacks to vote in 1790. And in 1860 two states still had property ownership requirements to vote I am saying deep cultural views are a more complex topic than you think.
PS: As one historian put it, economics pushed poor white farmers to abolitionism before the civil war. However, economics pushed those same farmers to discrimination after the civil war.
