I agree with everything you're saying. But I just wanted to mention that politicians are not actually required to swear in on a Bible. That's just what most use because of everything else you said. But every once in a while a politician will choose something different to swear on. Two I can remember of the to of my head was swearing in on Dr seues green eggs and ham and another one that swore in on a Captain America comic. Of course the religious nut jobs always lose it when that happens though
