Nothing but thieves, whores, liars, and murderers on the supreme court? Really, I don't think that's quite the way they put it.
Indeed, the First Amendment reference was intended to protect the churches from interference by the state, not to protect a secular state from religion. It is about freedom of religion, not freedom from religion. The modern extreme separationist notion was fabricated out of thin air by the liberal-dominated Supreme Court that unconstitutionally struck down school prayer in 1962.

Courts employ a uniquely serious, ritualistic and systematic process. It is within courts where each American's INDIVIDUAL rights and remedies are on center stage. We are individuals in that setting, Christian individuals and Shinto individuals, but we are first and foremost and ONLY Americans. Any icon celebrated in this STATE institution that infers a prejudice or advocation of any INDIVIDUAL characteristic, be it race, faith, ethnicity or gender, is a disenfranchising gesture.
