I have never read that sentnce in that entire content in any document. Please post this document for me.
Not one person has argued the fact that slavery wasn't a cause for secession. However you will find pleanty of argument it was the only cause of secession.
I have a question, Anderson being in Sumter of Febuary of 1861, if the South had freed every slave by March of 1861, would it have stopped the firing on Sumter in April of 1861?
Again I say you are only picking a portion of the entire argument to try to force the issue that "it was all about slavery."
Changing tactics and positions once again?????
