I think liberals and the ACLU are playing with fire. Law abiding citizens are ready to lose their temper. Americans will not accept the ‘balkanization’ of the US.
We have a template of this kind of thing happening in exactly the same way, when looking at some other countries around the world in recent history with similiar internal demographic and political situations that, could have been worked out, but devolved into out and out civil war.
The libs think they are being clever, but they are only starting to engineer the beginning of something that will surprise a great many people.
