Number one only 1 person can give Birth to you and thats the mother.
Unless your mother was the Virgin Mary, your father would have had a hand in it too, even if he wasn't the one carrying you around and shoving you out into the world simply because if it wasn't for his sperm, there wouldn't be any situation where your mother would be carrying you around and shoving you out into the world.
So, in a sense, he helped give birth to you too.
That said, to answer the question, yes, I respect my parents. They brought me into the world, taught me most of what I know, clothed me, fed me, paid for my schooling, broke their backs to support me (and my brother, for that matter, who was
never easy to care for), and were generally more trustworthy than anyone else I've ever met. As my father once said, "The only people who give a damn about you in the world is your family."
Of course, the end of that quote would be "and sometimes, not even then," and I'm not naive enough to think that
every family is like mine. Sure, if you've got due reason for it, then you're free to refuse to respect your parents, and there certainly are good reasons out there. However, if it's just a streak of teenage angst, then you'll eventually just sit back and take a look at who got you that far. *shrug*
