My niece and nephew are. I don't want to make more.Not a nice experience.
But now you know you are autistic, you can take steps to ensure any kids you have will have a good life.
And can I just point out the implication of your question ... that we and your niece and nephew would be better off not existing.
If I can stop it happening, I would. It's not something you would inflict on a child if you could prevent it.
