You sir are a crackpot. War is hell. Civil wars are the worst wars.
But not worse than subjugation
We are looking at a slow and horrible decline of the entire nation. At the end of it, we'll be as bad as Europe, except with free-speech being regulated by private companies, banks controlling who can and can't use their payment processors, Google deciding who can or can't get advertisement or funding for their websites, with millions of new Democrat voters flooding in from the borders.
It's either secession or we can just stop pretending that America exists anymore. Unless, of course, Trump pulls a Hudini at the last minute.
