Get called weird if they're lucky, get bullied and beat up constantly otherwise.
That was a big worry for me when my kid started going to public schools and going into grade 9+.. There were a few incidents where kids have been mean, but in general I'm actually pretty impressed with how well he's accepted and treated by other kids. It seems to be very different from when I was in school.
And yeah having things for them where they can be themselves is great. I can't even count the number of times my son has been asked to leave a program or sport or camp "to protect the integrity of our program". That's despite me being up front with his challenges, having a professional aide that attended with him, etc. For how much that impacts the parent I can only imagine how much it impacts the kids
