Your experience parallels quite well with the neurodiverse community too, so whilst I do not have the lived experience of your situation, I can empathise with the general feeling of not belonging. I guess this is why Star Trek episodes like this and other franchises (e.g. X-Men) that deal with fictional minorites work so well across so many real-world minorities and "out groups". They also provide a useful talking point to introduce the majority to the perspective of a minority.
I like to think that fans of shows like Star Trek are typically more aware of the diversity in humanity and more understanding of these differences.
I am sorry to hear that your daughter was treated like that, but am glad you have found a more welcoming community. Unfortunately there are parts of Australia that are just as unkind to anyone who is different, particularly some of the regional areas that aren't used to any forms of diversity.
