Your thesis was that home schooled pupils have a more difficult time aquiring social skills than their public school educated peers. How does this study (or this quote) support that claim?
The study/quote supports this by giving a rough indication of how most public schools are diverse places. Obviously, this doesn't "prove" the entirety of my statements, it just offers a small amount of support in the area of public schools being either segregated or diverse.

No. They study reports that schools are increasingly segregating along socio-economic lines, despite efforts to desegregate public schools by race.
