They both look like aliens.
That is the perfect public example of a relationship I cannot understand as a conservative woman. Why subject oneself to that? One can find enough marital discord even with a politically (morally) like-minded husband.
Furthermore, as a Christian woman, I take seriously that part about the husband being the head. That is an easy thing knowing my husband understands his part in those scriptures also. But a key thing is that he shares my conservative values. For me, it would be a major hurdle maintaining my part in marriage to a lefty. Again, a downhome argument for extreme vetting.
