In this context, "clean" is a religious concept, such as in "cleansed of sin by being baptized, saved, blessed etc. The question may seem very odd, but it is based on the scriptures, so carries some weight... In Leviticus chapter 12 there are the following claims about babies... If a woman has a baby boy, she shall be unclean for 7 days But if a woman has a girl, she shall be unclean for 14 days Some month's ago, I got a visit from a Jehovah witness named Mike. I asked him about these claims and he didn't have an explanation. So I suggested to Mike that it means that men are superior to women. He said he would have to talk to the Elders about it. A week later, he visited again ! He said he had asked the Elders. Their answer was, Yes, men are indeed superior to women !
