Casey Chalk explains in a Federalist column why religious conservatives worry about Democratic politicians.

“White evangelicals fear atheists and Democrats would strip away their rights. Why?” asks a recent op-ed in the Washington Post. The op-ed author, Paul A. Djupe, a professor at Denison University and scholar with the Public Religion Research Institute, offered two completely out-of-touch reasons.

The first is “because that’s what they’re hearing, quite explicitly, from conservative media, religious elites, partisan commentators and some politicians, including the president.” The second is an “inverted golden rule,” meaning white evangelical Protestants “express low levels of tolerance for atheists, which leads them to expect intolerance from atheists in return.”

It’s not about projection or an authoritarian impulse. Religious conservaties worry atheists and Democrats will strip their rights because they have repeatedly witnessed attempts, typically by Democrats, to strip them of their religious liberties.

Examples of Democrats’ attempts to gut religious liberties abound. Perhaps the most high-profile example was the Department of Health and Human Services’ (HHS) federal mandate in 2011, as part of the Affordable Care Act, mandating that certain employers provide all FDA-approved contraceptives, including abortifacients, in their health insurance plans. …

… This is why white evangelicals are afraid Democrats will attack their religious liberty — because they already have been for years. It also largely explains why this same demographic remains electorally wedded to Republicans, including President Donald Trump.

Notice that in almost all the above examples, it has been the judicial branch slowing the tide of anti-religious liberty initiatives. This has been the case even when activist judges at one level are overruled by more conservative judges at a higher level of the court system.
