Well, then one ends up like my mother who thinks that both are fully compatible without knowing nor CARING how different the two are. Instead she has an inordinate intrest in the practicalities in/of my life.
My sister's husband is an Episcopal Priest in Miami.
I have a brother though who manages to get around all of it by teaching Thermodynamics in France (I'm in the wedding if you look hard enough). His bride, a Southern Babtist got far away from that influence.
