You can’t cordon them off in “red" states. That’s ridiculous.
In reality there are no red and blue states. All states are purple. The red and blue is a political construct by simple majority. Many of those “red" states are “red" by very low margins, some less than 5%.
We live amongst each other too intertwined for this to be a viable option or even reasonable.
Would you sacrifice all the Democrats, liberals, progressives, and Independents in those “red" states?
Don’t be the pot calling the kettle black.
