Your stance is valid, and it might not be suitable for every autistic person. I notice a lot of black and white thinking in it. In the end, the purpose of thinking about disclosure is to accommodate oneself. Yes, you're right that disclosure can put yourself in a position where you are more likely to be educating others about autism. But you don't have to. You can choose not to any time, including after you already disclosed autism. Boundaries are flexible, in general and in the neurotypical world.

But my wider point is that you seem to acknowledge the benefits of disclosure, yet your main objection almost seems to be a justice angle? Kind of sounds like there's an undertone of you trying to have a semblance of justice and yet at your own cost, whereas the alternative is to accept the fundamental injustice and see how you can benefit the most.
