Miss Manners: Was I wrong when I confronted parent of noisy child in grocery store?

DEAR MISS MANNERS: In a supermarket, I had a conversation with the family of a very noisy child, about 6 years old. I protested the noise, while Mom defended it vigorously.

I walked away and continued my shopping. A few minutes later, the store manager stopped by to tell me that “disrespecting children” was against store policy and would not be tolerated. She referred me to the company website, but of course, I could find no such policy statement.

Why must members of the public be disrespected by unruly, misbehaving, noisy children, and then defended by adults who should know better?

I am not a fan of authoritarian or permissive parenting, and believe in the principle of a community of equal dignity. Sometimes, a parent should address the noisy behavior of a child rather than ignore it
