The mixing of government and religion can be a threat to free government, even if no one is forced to participate. . . . When the government puts its imprimatur on a particular religion, it conveys a message of exclusion to all those who do not adhere to the favored beliefs. A government cannot be premised on the belief that all persons are created equal when it asserts that God prefers some.
I do not expect that the mere fact that I was once an evangelical apologist and now see things differently should itself count as evidence that I must be right. That would be the genetic fallacy. It would be just as erroneous to think that John Rankin must be right in having embraced evangelical Christianity since he had once been an agnostic Unitarian and repudiated it for the Christian faith.
When reputable scientists correct flaws in an experiment that produced fantastic results, then fail to get those results when they repeat the test with flaws corrected, they withdraw their original claims. They do not defend them by arguing irrelevantly that the failed replication was successful in some other way, or by making intemperate attacks on whomever dares to criticize their competence.
