I didn't say Jefferson didn't write that in an early draft of the Declaration. He did.
You said it was taken out because Northerners wanted it removed.
So far as I've been able to find out, it was because South Carolina and Georgia planters wanted more slaves.
There is some discussion about whether Northern merchants opposed an immediate ban on the slave trade in the Constitution, but I haven't found that said about the Declaration.
It may be that Northerners and Southerners joined together to suppress the passage, I don't know, but it definitely wasn't a case of Southerners supporting an attack on the slave trade in the Declaration of Independence and the Northerners opposing it.
If you could reference where you read the SC and GA theory, I’d like to read it, but Jefferson’s papers and several others’ point to the decision to omit being made more by Northerners because they didn’t want to start the discussion over slavery BEFORE declaring independence and thus losing the southern states’ support before going to war.
It was not an attack on the slave trade, it was a list of grievances on the king, so your phrasing is misleading.
Jefferson, the lead diplomat of the State with the most slaves, thought it ok to put and leave in there, so I can’t see how you justify such an absolute statement as it “definitely wasn’t a case” of North forcing the issue. At least concede the possibility in fairness unless you have a source to refute it.
