One good thing about God belief of the Christian variety (if you can swing it) is that it inoculates you from other forms of irrationality. A nonbeliever in God is more prone to, say, succumbing to the delusions of Marxism or Big Foot than is a Christian.
But, of course, Christianity also comes with it’s own temptations to foolishness, which are legion (such as looking for Noah’s ark on Mount Ararat, seeing the Virgin Mary in a hanky, and pretending the Bible is inerrant and therefore of use for erecting hate on gay people).
And non-Christian Big Foot enthusiasts are somewhat inoculated from the arguments of, for instance, young Earth creationists. So it cuts both ways. When it comes to irrationality, people choose their poisons and antidotes.
Maybe the “inoculation from other forms of irrationality” argument for religious belief is baloney.
