Explain that?
Let me say that i am sympathetic to the idea of secession of conservative states on moral grounds yet from what i have read it "seems untenable." At least unless the people are willing to pay the price of it. Much has been written on this, such as argue that states overall - and the persons in them - are very pretty dependent upon the Federal government, from interstate construction to Social Security and Medicaid and Medicare, and such like.
While not paying taxes to the Fed would save money, yet federal funds make up a greater portion of the state's revenue of Red States, and taking over the costs of what the feds funds would be difficult.
And that federal funds make up a greater portion of the state's revenue of Red States

Louisiana and Mississippi are generally among the top recipients in federal aid year after year. That was true again in 2015: Federal intergovernmental revenues accounted for about 42 percent of their general fund revenues, the top shares nationally. Other states whose budgets are most dependent on the feds include Arizona (40 percent), Kentucky (40 percent), New Mexico (39 percent), Montana (39 percent) and Oregon (39 percent). That’s roughly twice as much as the least-reliant state budgets, which include North Dakota (18 percent) and Virginia (22 percent).
Public welfare is the single largest source of federal funding, primarily driven by Medicaid costs. Federal aid made up nearly two-thirds (64 percent) of states’ public welfare general expenditures, according to the survey data. The share was highest -- more than 90 percent -- in New Mexico and Ohio.
Federal aid made up for more than half of what the Census categorizes as “highway” spending in eight states, led by Rhode Island and Wyoming. Meanwhile, it made up roughly one-fifth of spending in Massachusetts and Minnesota. Most of this funding comes from the Federal Highway Trust Fund. It doesn’t include grants related to transit systems. - http://www.governing.com/topics/finance/gov-state-budgets-federal-funding-2015-2018-trump.html
Only 11 states depended on the federal government for more than one-third of their total revenues in 2001. By 2012, 24 states found themselves in this situation. State-by-state data from the U.S. Census Bureau, compiled by the State Budget Solutions nonprofit, illustrates the trend of increasing state dependence on federal financial assistance. Forty-one of the 50 states have become more dependent on the federal government since 2001 — with federal dollars accounting for an increasing share of their total revenues. - https://www.washingtonexaminer.com/exography-state-government-dependence-on-federal-funding-growing-at-alarming-rate
Of course, Fiscal Federalism should not be the case .
A black friend who grew up "poor" in Alabama about 50 years ago relates that they shared what they had - including spanking disrespectful kids (no sassing back), and "had everything but money."
Of course, then there is the need for national defense and projects (like the space program) that are beyond what must states can engage in by themselves.
And a independent state would also have to create their own currency and form trade relations, face disruption in critical interstate commerce and , the economic loss of US military base closures and federal employees and the closing of USPS offices. And perhaps denial of the National Guard. Plus demand by the Fed for compensation for the of land formerly operated by the US. However, I am only providing some practical reasons why secession "seems" untenable, but i again, i am sympathetic to the idea of secession and you are welcome to give input in support of it.
