I agree with those suggesting that you get legal council. You could even just do a consultation with a lawyer. That is often free. The reason that I say this is that your reasoning doesn't look like it would hold much weight from a legal standpoint. Many parents in other religions baptize their children (to save their souls) when they are infants. You need to lay out the difference in what it means when JWs get baptized, you need to lay it out in every way, and you need to do so in a way that says, "This is what it means in this religion."
Your writing... it needs a basic grammar and spelling check. It is mostly emotional and doesn't make a lot of sense from an outside perspective. The judge is human but they will also be coming from their own background. You have no idea what that is. But, guaranteed they will have no idea how things work within the Jehovah's Witnesses religion.
You would be wise to get a lawyer to cover all your bases, and then write your own heartfelt response to be included. This way, the judge will see that while you are emotional.. your desire for your children is reasonable and not just motivated by your personal feelings about.... whatever. The judge will get to see a balanced perspective and your very personal perspective. Both are important and they should be presented together.
