On introspection, this does agree with my preferences, yes.

That does complicate things -- I'm not sure how to resolve this one.

I think we are using the world "rationalist" to cover too many meanings. One highly socially useful meaning for the word would be "person who can be reliably expected to speak the truth". Whatever you choose to call those, it'd certainly be useful to have some around for any society you'd like to build. We would want to have some tests to identify them.
