I don't think the argument had anything to do with isolation. Your reply sounds stereotypical. Stay-at-home parents - and similarly, home-schooled children - usually have a richer and more vibrant community than schooled children and the average 9-5 working parent.

I've met hundreds, and it always strikes me as a more ideal life, because it's steeped in strong community.

Of course there are the isolation exceptions that make headlines in news media.
