Basically bringing the bible/prayer into public schools, the extreme side of abortion restrictions, manogamy/abstinence despite human nature, etc. Those are some of the examples I'd find under theocratic rule, and it isn't entirely religious conservatives imo. But what is unique about the republic was the separation of church and state. Therefore when it's conservatives that do it, it contradicts the founders vision. The recent Michigan Republican on banning the pill, or Abbott saying he's working diligently to prevent rape (vs it being covered in abortions). It comes across to me as religious extremism and cow towing.
