Neither of those are examples of strawman arguments. One was a paraphrasing of what you said, the other isn't a strawman, just the truth.
But you made a point, that was an old point. Again, as I said, there was 20-30 years of NE making money on Slavery, then the US abolished the African Slave Trade. That's not to say that people weren't making money on slavery in NE, but it was certainly not prominent. The discussion was about the time at Civil War, not about the 1700s and first decade of the 1800s. You attempted to deflect shame by pointing to a time before was cited by the OP.
As far as slavery being abolished in NE, it was abolished by 1785, first by Vermont in 1777 (before it was even a state), NH and Mass in 1783 and CT and RI in 1784. As far as when slaves were emancipated that was after the Civil War, because most states still allowed slaves from other states to come with their masters. One of the reasons that the civil war broke out was because states started passing laws that wouldn't allow for that.
Like I said.... And you can't even get my point right.
Try this for CT (for instance):
1784
The “Gradual Emancipation Act” declares that the children of enslaved African Americans born after March 1, 1784 were to be granted freedom upon reaching the age of 25.
1788
State legislation outlaws the slave trade in Connecticut, prohibiting the import of Africans and the export of African Americans for sale, and requires every slave owner to register the births of every child born into slavery in their household with their town clerks.
