And then people can see for themselve which one makes sense.
The idea that every single religion in the world needs to have a placard is not reasonable. Of course liberals are not reasonable.
It wouldn't hurt, but there's not enough room unless a whole wing of a building is dedicated to that purpose. Actually, it would be interesting, because every monotheist religion in the world has the same basic moral absolutes.
The idea of an amendment is perhaps admirable, but the problem is so deep, that those who hate God no matter what name He is called (but have an strange attraction for Islam, oddly enough) will worm their way around this one, too. I mean, the amendment protecting religious expression is already as clear as day.
