and what about the imposition of discomfort upon a child who is told they cannot express themselves heartfully except in certain acceptable environments? Can we not recognize these children as strangers who don't want impositions placed on them any more than some of us wish to be imposed upon?

Seeing someone glare at a 'stranger' child like they want it to die does a lot more towards giving ME a bad day than I imagine having to hear a child shriek happily for five minutes does for you.
