That's fine.Generally, if it's not a locked post it's all right if you quote it, but thank you for asking permission anyway. :)
Oh, and I'll doublecheck with Luai too, to be sure. She has been active in Autism Advocacy/Autism Rights stuff in the past, though, to a much much greater extent than I ever have actually, so I'm inclined to think she'll be fine with having her words and opinion shared in this context.
Okay, Luai says it's fine, too. Quote away.
