““But what is normal? Normal is that which already exists, the prevailing condition. But normal is also normative — an expectation, the thing to be wished for. The norm is a double-edged sword. A person can be measured against that which exists, in which case she will be found to be normal and healthy, therefore good. Or a person can be measured against an expectation and found to be wanting. The norm can be changed at will. For those on the inside, the double-edged sword is a defensive weapon. For outsiders, it's a terrifying threat.””
