In order for it to be a blatant tangling of religion with government there does need to be the coercing of people into adopting Christianity or flagrant abuse of other religions (and by flagrant I mean unfair persecution or outlawing of other religions) or at least unfair prejudices towards one religion. In this case there is not, so there is no breach of the Clause.
It does not need to be one where there is coercion of people towards a religion. If I'm not wrong, cases like Lee v. Weisman prove so.
Also, I think it does show unfair prejudices towards one religion, in that the authors refused to sponsor other religious books, even on the grounds of fairness and broad representation. If they had the intention of finding a book that represents the people, why not find a neutral historical novel like other states? Even if they don't represent everyone, it's likely to be less divisive.
I believe it is discriminatory to use such a divisive book to represent the population, even if much of the population (~60%?) believe in it. It unfairly leaves many in the lurch, because they're not represented by the text. Even though there are no tangible effects, I would feel disgusted that the government chooses something to represent the state and declares that it's very representative when it so blatantly does not represent me at all. Furthermore, just because it represents the majority of people, does not mean it needs to be given official weight. But that doesn't really matter, it's not the main crux of the discussion at hand; I don't think anyone here even thinks it's a good idea.

Violation of the Establishment Clause is generally tested against a Lemon Test (Of course it's not the only test though), with three criteria. If any of them is ruled to be breached, then it must be struck down under the Establishment Clause :
a) Must have some secular, or non-religious legal purpose; - Arguably, it can go both ways. Does it have a non-religious legal purpose? Perhaps, by giving the state a thin degree of representation. But it does so via a religious fashion. So it can swing both ways.
b) Must neither promote or inhibit the practice of religion; It certainly does not inhibit the practicing of any religion, but it can be argued by opponents that it promotes the practice of a specific religion. The book is after all, given official weight, and though the law does not actually actively promote religion, previous precedent cases showed that an act that violates the Clause does not to do so in such a fashion. In the case County of Allegheny v. ACLU, the Court ruled that there was a violation of the Establishment Clause as there was promotion of religion, by conveying "a message that a specific religion is ''favored,'' ''
referred,'' or ''
romoted'' over other beliefs.", because the "
rinciple or primary effect" of the holiday display was to advance religion within the meaning of Lemon v. Kurtzman (The original case where the Lemon Test was derived), when viewed in its overall context. This is not helped by the fact that the Bill sponsors have openly and adamantly came up against sponsoring other religious texts similarly.
c) Must not must not foster "an excessive government entanglement with religion." - Again, this is arguable, to many it will be excessive government entanglement with religion, as they aim to enshrine a very specific religious text that far from all Louisianians believe in as the State Book that represents them.

I'm very interested in seeing how it all turns out, and how the courts rule, especially given the highly charged political situation now. Also, apologies if I get the legal jargon wrong, I haven't actually began my law course, just reading up and stuff.
