Totally agree with CSM.
Unless you are one of the Lee cocksters, by saying LKY is your Father is a slap across the face of your real Father.
besides our physical dads,there must be a greater spiritual dad,proverbial dad,ideological dad,existential dad,rich dad,poor dad we must all aim for in order to achieve the highest tiers of the maslow's hierarchy in life,more than just the dad who gave us his blood and sperm.
when darth vader told luke skywalker "i am your father",indeed he was not just speaking in the literal sense but also allegorically to all mankind,for indeed he is the "father" who would bring balance to the force by giving birth to luke skywalker.
