Do you thank your parents every day for bringing you into this world? Do you thank them every time something good happens to you simply because they raised you as a child? Do you show complete and total obedience toward them no matter what they ask of you? Do you throw away your life plans and dreams to do what they want? The answer to all these questions is no. Just because our parents brought us into this world and raised us, does not mean we owe them anything. We did not ask to be born. We did not ask to be raised by them. They did it of their own free will.
In fact, I’d argue that raising a child simply to have them appreciate and show gratitude toward you for the rest of their lives is evil.
Your parents had a child and raised you because that’s what they wanted to do. Just like god supposedly created us because he wanted to. If someone does what they want to do, and it somehow affects your life, that doesn’t mean you magically owe them anything. This line of thinking is reminiscent of those statists that argue if you don’t like paying taxes then you should just leave. It’s a weak argument.
