I really can’t point to any document stating that Parliament refused to recognize the CSA because of slavery. I suspect that such a document does not exist for the very simple reason that it never got to a vote in Parliament. Would they have recognized the CSA if it won? That would be very likely - hatred of slavery only goes so far when compared to a fait accompli. I think that the important thing is that they did not recognize the CSA when it could have made a difference in 1861 or 1862.
“I think that the important thing is that they did not recognize the CSA when it could have made a difference in 1861 or 1862.”
I do not dispute that at all.
