Are you sure?
Not only do forced rapes occur while girls and women are unconscious (beaten or drugged), in some states those same girls and women would be forced to bring the fetus to term. Not only that, but the rapist would enjoy parental rights, including visitation in some jurisdictions.
Ditto girls and women with developmental disabilities, who may not understand the implications of sexual intercourse.
Are you one of those Republican men that believe that "real" rape doesn't cause pregnancy?
