She already believes that I can defend my views better than she can her's. She probably even believes that my views are closer to the truth.

I'd be curious to know what sort of power dynamic you have. My spouse believes I am more rational and intelligent than s/he is - but s/he's still the one who makes the decisions. I advise - my spouse decides. We both like it that way and we've had a successful and happy relationship for more than a decade. Now that I think about it, this is reminiscent of Eliezer's "Three Worlds Collide". You want to keep the rationalist cultists around - but you don't want them in charge :p
