I just think the idea of slicing off a part of the USA to create a new country just for the white supremacists is a dangerous one: once they're their own country you lose control of who they make alliances with. Just imagine if they made an agreement with Russia or China to allow a military base there - it'd be like the Cuban Missile Crisis but just a bit closer to the USA...
I can't speak for Jay, but while I 100% advocate for these "people" to have their own country I wouldn't advocate for giving them any slice of the USA. They're free to go carve out a place for themselves in whatever fascist dystopia will have them.
The racists here have held the country hostage from literally the beginning. Without concessions for their institution of slavery they were unwilling to even form a Union in the first place. Compromises with intransigent racists in 1820 and 1850 helped preserve "unity", but at the expense of millions of enslaved people and their descendants. The Civil War, and the horrific aftermath perpetrated by the racists was just another example of them being willing to sacrifice absolutely any political ideal in order to preserve their racist status quo.
More compromises for the sake of "unity" and we get nearly 100 years of Jim Crow segregation and, like Jay said, the exact same battles with the exact same types of people from the previous century to end it. While much progress has been made since the 60s, I'm fed up with compromise. I don't want "unity" with racists. If they don't want an America that lives up to the promise of 1776 then they shouldn't be here.
I know with our 1st Amendment freedoms it is difficult to legislate away racism and similar bigotries, but it is long past time that these people are forced to accept that the world they want is not acceptable and will not be tolerated. If that means forcibly expelling people who have demonstrated for centuries that they're unwilling to be a part of an inclusive world, then I'm quite willing to explore how that might be accomplished in a way that doesn't threaten our basic liberties.
