Only the female who bore us can vouch who is the father. No need to go in detail. Atleast u r given life, get satisfied with that. Rishi moolam/ Nadhi moolam is not for open arguments. Who is sure about their identity apart from our mothers. Still they have to be revered for their sacrifice to bear us for a prolonged period even though it is for few moments satisfaction. Accept what we are are. No body can call anybody in some other name as nobody knows who we are. atleast we must be pervertly satisfied that we have some identity. Iam not blaming whole of the mother hood & mankind. But we have no authority to call somebody in names. Love is utmost. love your neighbour thee. Sorry if I have offended your views.
