The harm is in your being treated like a number, instead of as a unique human being, with a unique story. In the next construct we considered, the internalization of structural violence, we need to reintroduce the the uniqueness of individual response to the social context. In early childhood, frustration is a part of our daily growth. We encounter barriers, we encounter language, we encounter the need to persuade others to do what we need. These early experiences shape our response to frustration.
Criticism entails frustration.
Having made the effort to do something I am now told that effort was not as it should be. We speak of learning as one uses the criticism to correct the effort. But we do not all learn in this way. If the criticism is painful enough, the lesson learned may be internalized anger. And if our coping mechanisms have not kept apace with our intellectual growth, it may be anger not learning which is internalized.
