You seem to believe that Leviticus 18:7 says that a man should not uncover
his father and mother's nakedness because the you form of the verb is
masculine singular. You think women were not specifically forbidden to their
fathers. Maybe there is another reason. I don't know.
Anyway, if that is the reason, then women would also be allowed to kill and
break some of the ten commandments which are also in you masculine singular
verbs.
