Sigh..how to persuade those that it was of states rights, is a useless endeavor.
The slavery issue was only brought about by the continuous efforts of the anti-slavery lobby itself in the political forum.
Abe Lincoln, himself, did not consider it an issue, until forced into a corner to be re-elected.
And may we never forget that when the draft was instituted by the Union, there were riots in Manhattan where free negroes were killed in protest.
Sorry, but to yall who consider slavery to be the main issue of the Civil War....you are foolishly mistaken.
