I would imagine a significant percentage of people leaving blue states are actually red and frankly are leaving out of disgust. Also, those moving have the resources to move, so you don’t want to block that from red states. Several large companies have moved out of CA to Texas this year alone, including Oracle. People with low incomes won’t have the money to flee blue states and will get welfare.

I think strengthening Conservative culture in red states is very important. What you want to stop are the mechanisms for communism’s spread, for example in the schools, through terrible brainwashed teachers and curriculum. Average Patriots need to consider getting directly involved in local school districts as volunteers, school board members, teachers, etc. Alternatively, getting involved with home schooling. All of the public schools will end up with forced vaccinations that will increase in number every year, so there will likely continue to be a large flow toward home schools.
