According to this site New Jersey reduced the number of slaves from 12,000 in 1800 to just 18 in 1860, while the number of freed-blacks rose from 4,000 to 25,000. So by 1860 New Jersey had over 1,000 freed for every slave African American. In South Carolina, by contrast, the number of slaves rose from 150,000 in 1800 to 400,000 in 1860, while the number of freed-blacks rose from 3,000 to just 10,000. So South Carolina's ration of slaves to freed-blacks remained about 40 to one.In view of the facts, your concern for New Jerseyans' "hypocrisy" is misplaced.
It is just this sort of failure to understand the point that makes it futile to attempt a discussion with you on this topic.
When you are talking about moral absolutes, 18 slaves in New Jersey is hypocrisy, while 400,000 slaves in South Carolina isn't.

"When you are talking about moral absolutes, 18 slaves in New Jersey is hypocrisy, while 400,000 slaves in South Carolina isn't." A Confederate declaration of war against the United States (May 6, 1861) is a moral absolute.
The rate at which New Jersey & other Northern states gradually abolished slavery in the early 1860s is not.
