Of course, O’Reilly is totally incorrect about the law. The decorum of the capital building was violated exactly the same by the atheist sign as the creche. The establishment clause of the 1st amendment requires that any speech being permitted by the State in the capital building needs to be vetted under a premise other than religion.
This is exactly what should have happened: the only rational way to uphold the establishment clause is to prevent all religious speech promoted by the State. Why? Because there are BILLIONS of religious viewpoints and not enough room to hold them.
This is exactly what happened here.
Poor Megyn Kelly. O’Reilly set her up disrespectfully by calling her misguided, and in a previous encounter he called her a “cookie” or something. He has been misinformed by whomever he got his information from; but it’s important to keep in mind that the State shouldn’t be respecting any establisment of religion over any other. That means all or nothing.
All is reliably impossible.
