Should we stone women who are not virgins when they get married?

If the bible is not the word of god, then there is no reason to allow it to be the final authority in our lives. Any book that says we should stone women who are not virgins is not a book anyone should should listen to. In fact, any book that says we should stone anyone should be ignored. Why not stone men who are not virgins? This book of perfect morality is perfectly willing to let men screw around without killing them. It is completely misogynistic. How does stoning any non virgins help society? On what basis should we assume a woman is not a virgin? That there is no intact hymen? Since women can break their hymen with normal physical activity, we could be stoning virgins who ride horses or do gymnastics.
