I don't think secession is a viable option. We are very interspersed even in the most politically polarized areas. I am not sure about our nation's future however. I feel no commonality with today's progressive movement. In reality I am repulsed by them and it is hard to live side by side with someone you feel that way about.
I am diametrically opposite to their views on abortion, immigration, wealth redistribution, BLM and Antifa idiocy, gun rights, their ridiculous sexual orientation nonsense, attack on energy production, over regulation, scope of governance, property and business owners rights and their negative attitude towards the importance of the traditional family unit.
They bristle when the concept of an American culture is held in regard in favor of an anti American slant. They worship at the altars of wokeness, atheism or some radical cult of animal rights or mother earth crap. Christianity of course is verboten in their world.
As each year passes we grow farther apart anf they seem more foreign. In years past as the radical left aged they became more sane as wisdom and the realization that the taxman really wasn't their friend settled them down and made them more tolerable. Now the stupid seems to deeply rooted for any wisdom to creep into their warped psyche.
