Technically, England* and Sweden* (for examples) have a national religion. However, both societies are highly secular, and no religious edicts are enforced. Despite the fact that America technically has a secular government, religious pressure and influence in the USA country are far greater than in England or Sweden. Thus, I prefer the technicalities of how religion is SUPPOSED to behave in relationship to our government, but the actuality is that some countries with official state religions are actually MORE secular.

* Note: I used those two as examples because I'm more personally familiar with both of those societies than with other societies.

Now, I have a problem with any theocracy or state religions in principle, but I have a REAL ISSUE with theocracies that enforce a religious code on all residents, regardless of religion. I also have a problem with countries that prohibit religion or oppress members of certain religious groups as long as those groups aren't hurting anyone.
