There shall be a rebuttable presumption that it is not in the best interest of the child for the court to place the child in the custody of or to grant visitation rights to a person that the court has found by a standard of clear and convincing evidence to have committed an act of rape or incest against the other parent that resulted in the conception of the child. The court may revoke visitation rights upon such a finding.
