1st Amendment up for debate again

Slate's latest coverage of the Sumpreme Court's latest case raises some pretty good questions. The article is also covered by the First Amendment Center pretty well.

After reading these articles and trying to grapple with the Establishment Clause of the First Amendment, I wonder if a solution might not be to just put out a disclaimer. Because you could easily argue that religious words and/or symbols are art, couldn't or shouldn't public places simply remove any possible endorsement of the religion. For example, "The thoughts or ideas reflected by the historical documents and displays in does not necessarily reflect the beliefs of the state." Inevitably, I am assuming the Supreme Court will shoot down any efforts to deliberately display something (intentionally establishing religion), but I can see them allowing, say the Texas statue, and ask for a disclaimer.
