So am I. Thank you for posting this.
In addition to being strange, the author is just plain wrong. The U.S. military "wouldn't mow down San Franciscans"? Oh yes it would, and there would be milllions openly volunteering to join the armed forces to help cut down any such "secession". What Sale seems to forget is that even such ultra-liberal bastions as San Francisco have population that are roughly 25% Republican, give or take. None of those people would ever want to secede, and unless such a movement was essentially unanimous in any given area, the local government would have no moral standing to attempt to do so. That other 25% would have the right to compel their nation to come to save their freedom and soverignty from the tyranny of the majority, and we as Americans would have the unquestionable responsibility to save those people's right to live as Americans under an American flag. The Constitution's pretty clear about this.
If they secede let em go by counties, sparing those of us in "blue" states, but NOT in blue territory. If you look at the last election map, that leaves the Left a few South African style "homelands" where they can not feed themselves. Hell they will need a passport to get to the Walmart....
