Yes, that doesn't precisely support the claim.
Traditionally, christianity has made people think that masturbation is sinful.
That a woman is dirty or evil during her period is another old religious theme.
The outcry against abortion is predominantly religiously motivated.
Most people believe it is wrong to kill. Most also believe that if you have the chance to save a life and do nothing, that is only slightly less wrong. Particular circumstances aside.
If terminating the development of a joining of cells that can potentially become a human being is wrong, shouldn't it also be wrong to stand by and let the opportunity to create a human being pass by?
Doing nothing when you don't intend to get pregnant is fine.
Doing something when you didn't intend to get pregnant, but did, is supposed to be wrong, according to some. Either way, some cells didn't become a human being.
It may be that the same arguments that go against abortion also go against ovulating. I am wondering if the abortion controversy may be a form of religious oppression..
