Yeah, yeah. You're obedient to your father until he says something you don't like and you reject it. Then you deal with your disobedience by concocting all kinds of theories about who your father really is and how that other guy who appears to be your "father" really isn't - thus keeping in tact your compliance with your warped sense of "obedience."
Take a hike with your "impious bastards" bit.
With all due respect, I find this analogy rather lacking...
Was your father elected? Do you get a new one when he dies?
If your parents divorce in civil court and your mother "remarries", are you not allowed to question the legitimacy of this marriage? Can you not hold the opinion that this man is not your father, nor a legitimate authority figure to you?
By this logic, it seems that your position may be that you should recognize him as being your legitimate new father but resist his authority.
I tend to try to stay out of this topic (not my circus not my monkeys

) but this did kinda stand out to me.
