...I hope you don't believe that most of us here agree with all the racist and/or pseudoscientific and/or politically regressive and/or exclusionary opinions voiced above.
...it's sad, but lots of people send their kids to private schools expressly to keep them away from kids who have (ahem) "issues." Private schools are under considerable pressure from those parents to keep out kids who are regarded as troublesome, different, what have you--they typically have little incentive to help or serve those kids.
Often kids who have unusual needs really will do better in a public school, where at least they have their civil rights to fall back on.

Wow! And you accused me of being making regressive, biased claims based on pseudoscience! Can you please show me some peer-reviewed studies demonstrating that private schools trample the civil rights of their students? And that so many of us private school parents are putting considerable pressure on our kids' schools to keep out kids who are "troublesome, different, [or] what have you?" Or are you just allowed to make unsupported claims because you believe them?
I've looked at a lot of schools for my kids over the years (30+), and the only one I encountered that expressly didn't want kids with disabilities was a "high-performing" public school. They were honest with me: "our test scores are high because we don't admit kids with disabilities. They can get services at the other schools in the district."
The only point I'm trying to make here is that your generalization doesn't hold water. I expect that the knife cuts both ways on this question.
Sheesh!
