The only joke here is that you think a tariff that was written around January of 1860, passed in the House in March of 1860, passed in the Senate in February of 1861 and signed into law a few days later was somehow designed as a response measure to a war that began in April 1861. Not only does your interpretation of the Morrill act defy history as it happened. It also defies the timeline itself!
But please do proceed - I find it highly amusing to observe the degree to which you are willing to embarass yourself rather than admitting your ignorance and error on the tariff issue.

Do you not find it the least bit strange that a bill that you claim was to finance the war was taken up by congress well over a year before that war ever started and long before they even knew there was going to be a war? If the things that you claim about the bill's purposes were true (and they are not) Rep. Morrill must have been consulting with his psychics!
