Hi, welcome to the real world where words have meanings! A dysfunction is something that causes a person suffering. There's nothing wrong with having a dysfunction, and it's exactly what therapy and transition surgery attempt to address. It doesn't have Jack **** to do with any social norms, it has to do with whether a person can function or not. Can they eat, sleep, work, experience a range of emotions, are they forming relationships, are they hurting themselves, and infinite more questions have to be addressed. So lose the attitude and at least get the slightest little sliver of an education on the topic.
