Analogy for how my atheism works

This analogy may not apply to everyone in the world's atheism, and it obviously won't work with everyone's gender identity. But I'm putting it out there because it might help explain the concept to a lot of people.

I am atheist the same way I am female. I just am. I can't be anything else. I could perhaps pretend to be something else if I wanted to, but that wouldn't actually make me something else.

Some people try to talk me out of my atheism because they perceive there to be a god. But no matter how strongly they believe there is a god, that isn't going to make me capable of the same faith. (Believe me, I've tried.) This is just like how no matter how strongly other people believe themselves to be male, it isn't going to make me male.

Some people try to convince me that I will one day find religious faith on the basis that they themselves used to be atheist and then found religious faith. However, the fact that they found this faith doesn't mean that I will. There are people with female bodies like mine who have come to the realization that they are actually male, but that doesn't mean that I will one day come to the same realization.

Some people tell me that it's irrational to be atheist because one has no way of knowing for certain that there is in fact no god. I could respond to this by citing empirical evidence, but ultimately the fact that it cannot be proven for certain is irrelevant. I simply cannot be anything else because I am incapable of religious faith. Similarly, I can't prove or justify my gender. I could point to empirical evidence of my physiological sex, but I have no way of proving that I do actually identify as female. But I simply cannot be anything else.
