The current secession advocates reveal nothing except their own historical ignorance. The issue of the right of secession was conclusively decided when Lee surrendered to Grant at Appomatox Court House, April 9, 1865. It is a dead letter legally. It is also significant that the greatest number of current proponents are from states in the old Confederacy or the guns and bible West - none of which being characterized as places known for their first-class educational institutions.
I'd like to see some of these yahoos try to secede - it would be most enjoyable watching them be put down by law enforcement and, if necessary, by the U.S. Army. Grow up and quit acting like spoiled ten-year olds throwing an extended temper tantrum.
