The source for this inanity is the тαℓмυd, the same source for partial birth abortion BTW.
(Where a pre-born child does not become "human" until his head emerges from the birth
canal, consequently the killing of the child in partial birth abortion occurs while the child's head
is still inside his mother's body, and they say "it" was not a child yet, so it wasn't "killing.")
In the тαℓмυd, a Jєω (often times a rabbi) can sɛҳuąƖly molest a girl, and so long as the girl is less than 2 years old (as I recall -- maybe it's 3) the girl will still be a "virgin" when she recovers and grows older.
The тαℓмυd is the source of many vile and depraved ideas many of which are much worse than this.
It is a really disgusting set of writings.
There are at least two versions of it, so if you go to your public library, don't expect to find the really bad version there.
And if you ask the librarian about the other version, they won't be able to answer your request because they don't have one listed.
