This is “why it’s an issue to put an autistic person’s photo on the web without their consent” post.

-It’s not imposing anything on anyone to ask that people treat autistic people with a basic level of respect and acknowledge their autonomy. Especially if one is claiming to be said person’s “best friend.”
-I highly doubt that you would enjoy being an “inspiration” to people just for existing, or for doing something that isn’t particularly note-worthy. I doubt even more that you would appreciate having a “friend” who values your relationship primarily in terms of how much you “inspire” them.
OP, I am autistic. I second everything Rose and Allies-Person said. Since she is a minor, you should have consent from her and her parents. What you are doing is wrong. If someone did this to me and I found out, it would end the friendship. Treat her as you would like to be treated, as a person.
