TBH, she was on my shitlist for a while about 10 years ago when she sort of took on the role of spokesperson for HFA. She gave a whole lot of interviews explaining that people with autism are visual thinkers. Only, they aren't. But a lot of DS's teachers saw her or read one of her books and tried to shove him into Grandin's model. It's kind of funny that these people took the word of a strenger with poor Theory of Mind (i.e. the ability to understand that other people think differently than they do) over the performance of the kid they were actually working with IRL. I suspect she's had others point this out to her because she has since backed away from speaking for all on spectrum as she used to. She also seems to have gotten more comfortable with public speaking- her more recent talks and interviews are easier to watch than the older ones.
I know people who know her including a retired OT who worked with her back in the day. She's a sweet and lovely woman, one of my forum buddies sent her a note after the Claire Danes movie came out thanking her for sharing her story and Dr. Grandin sent her a nice handwritten reply. I'm told mom's less "nice" but that her impatience with behaviors is probably a big part of why her DD is such a competent individual. Both are engaging and interesting speakers. You should enjoy it.
When DS was younger, I wasn't sure he knew who Temple Grandin was. I mean, I never held her up as a role model or anything. Turns out, he read one of her books in 9th grade and later shared with me that his brain didn't work anything like she described. He also though Curious Incident in the Night was a load of crap. At any rate, when he was about 16 and working on his Eagle Project we went to a Tractor Store to buy tractor paint for the project. We walked in, DS looked at the clothing displays and said to me "I think we figured out where Temple Grandin buys her clothes".
