It already has bitten them. The states with social policies that most closely adhere to conservative religious principles are the worst places to live. And they blame the media and the government. It could not possibly be that their policies are irrational, are ill-suited to modern life, and just plain don't work.
Their prejudice forces liberals, gays and immigrants to move away, the real "job creators" and the tax base disappears and most vibrant part of the local economy collapses. More divorce, family violence, poverty, school dropouts, etc. are the result. Then the meth labs and massage parlors move in. Seriously, it is like they think god wants them to be poor, uneducated, addicted and suffering from untreated STD's, since that is exactly what their policies lead to.
Fine. Just stop taking money from the evil government for farm subsidies, social security and disability payments. Stop using the military (also part of the evil government) as the high-tech welfare and employment program for your communities. Be against birth control--have a child every year that you cannot feed, and see who you will be able to hire to teach them all in your Christian schools for sub-minimum wages. Luckily, crime will go up enough for you to get a nice, full to bursting private prison (also subsidized by the evil government) that will hire the local folks who don't have police records themselves.
Also, their ignorance is astounding. One southern community did decide to refuse all money from the evil government when Obama was elected, because he was the antichrist. And they were shocked, shocked to learn that they had eliminated the federally funded meals on wheels program that their elderly population depended on for food
When some other politicians passed laws banning what they thought was "sharia law" they found they had also banned policies based on the bible.
