I responded slow to you on this, as I'm not entirely sure on direction.
I certainly was too vague in my opening post. Not wanting to be around someone is, all told, fine. When I say "can't handle kids being around," I'm largely talking about the ones that have adult tantrums.
My main concern is we seem to have taken the view that parents are "outsourcing their responsibilities." But, so has society, as a whole. It isn't any individual's responsibility to make sure kids have a safe place to be kids. Both loudly and quietly. It is, ultimately, everyone's. As such, if you build a place that you don't let kids in, don't be surprised when the kids don't know how to behave in that place.
So much "public space" has been reduced to isolated pseudo private islands where people want to be out, but also want everyone else to not be there. I'm not saying we should all be one communal table, but I do hate that we all seem to always want the private booths, if you will.
