I can understand why people raised as Catholics would be so immune. But if you're making a decision to convert to Catholicism, presumably you like the whole integrated, no-exceptions theology.

As with most, if not all, religions, one would be surrounded by people giving off signals to the effect that this or that contradiction is no big deal. Combined with a relief from whatever discomfort remains from childhood indoctrination, plus the halo of being "intellectually formidable," it seems a rather seductive package.
