The moment you start bringing your personal belief system into governance, then that’s the end of pluralistic democracy. We have words for governance like that and they’re called dictatorships. You have a belief system, you have a philosophy, and that philosophy has some adherence and others have their own philosophies. Those are your personal truths. One of them is, “Jesus is your Savior.” I’m not going to say that Jesus is not your savior. That is your personal truth. But, in a country where we have different religions, if the person who said: “Jesus is your Savior” is going to govern a pluralist country, then their legislations must be based on objective truths, not personal truths.
And personal truths are not only religious. You can have political personal truths. You keep those to yourself or your political group. But, to impose them on others is to do away with the freedom that a free democracy gives you. Now, getting back to your point, we have people in Congress whose job is to pass laws. If they pass laws based on things that are not objectively true, that’s the beginning of the end of an informed democracy.
