The Bible is very clear that most divisions between people are entirely artificial. Such arbitrary distinctions shouldn't influence our choices when it comes to things like marriage and romance. However, in some areas it's wise to maintain separation. It's not a good idea for people with entirely different religious views to date, for example. Even worse is when a couple realizes that one of them knows how to think, and the other is a complete dope.
This kind of interrational dating only causes problems. An interrational relationship occurs when there's a noticeable difference in two people's ability to apply common sense and logic. It's important to note that "reason" is not exactly the same as "intellect." Some otherwise intelligent people are nonetheless
deeply deprived of reason. Rationality also comes in many forms, so it's possible for two people with different styles of reason to cooperate very effectively.
Paul warned against being spiritually "unequally yoked" in a relationship. Similar problems exist when there's a gap of reason between romantic partners. One member inevitably winds up trying to explain things, fix messes, or otherwise deal with whatever stupid stunt the other pulled. The less-rational partner might or might not be aware of these stresses. When they are, of course, they tend to become defensive and unhappy.
Things like skin color and heritage are ultimately meaningless when it comes to relationships and spirituality—which is why there is no reason to oppose
interracial dating or marriage. Interrational relationships, on the other hand, must be avoided. At the very least, it's better to let those capable of common sense and reason stick together, while blithering idiots and morons mind their own business.
