I'm just thinking about how a person looks like a female, but has a dick and has XXXY chromosomes should address themselves.

Persons with XXXY chromosomes have a difficult enough time as it is in life without claiming they look female, and suggesting they should be seen and spoken of as not male or as less male than other persons of their sex. Persons with XXXY chromosomes are 100% male with a complex medical condition that affects only males. They deserve compassion as all persons with congenital diseases and developmental disorders and anomalies that mark them as "different" do, which means not using them as props in convos and arguments about gender ideology.

48,XXXY syndrome is a chromosomal condition in boys and men that causes intellectual disability, developmental delays, physical differences, and an inability to father biological children (infertility). Its signs and symptoms vary among affected individuals.

Most boys and men with 48,XXXY syndrome have mild intellectual disability with learning difficulties. Speech and language development is particularly affected. Most affected boys and men can understand what other people say more easily than they themselves can speak. The problems with speech and communication can contribute to behavioral issues, including irritability and outbursts or temper tantrums. Boys and men with 48,XXXY syndrome tend to have anxiety, a short attention span, and impaired social skills.

Given their difficulties with verbal communication, raising the issue of how these boys and men "should address themselves" strikes me as inappropriate, insensitive and downright offensive.

48,XXXY syndrome is also associated with weak muscle tone (hypotonia) and problems with coordination that delay the development of motor skills, such as sitting, standing, and walking. Affected boys and men tend to be taller than their peers, with an average adult height of over 6 feet.

Other physical differences associated with 48,XXXY syndrome include abnormal fusion of certain bones in the forearm (radioulnar synostosis), an unusually large range of joint movement (hyperextensibility), elbow abnormalities, curved pinky fingers (fifth finger clinodactyly), and flat feet (pes planus). Affected individuals may have distinctive facial features, including widely spaced eyes (ocular hypertelorism), outside corners of the eyes that point upward (upslanting palpebral fissures), and skin folds covering the inner corner of the eyes (epicanthal folds). However, some boys and men with 48,XXXY syndrome do not have these differences in their facial features.

48,XXXY syndrome disrupts male sexual development. The penis is shorter than usual, and the testes may be undescended, which means they are abnormally located inside the pelvis or abdomen. The testes are small and do not produce enough testosterone, which is the hormone that directs male sexual development. The shortage of testosterone often leads to incomplete puberty. Starting in adolescence, affected boys and men may have sparse body hair, and some experience breast enlargement (gynecomastia). Their testes typically do not produce sperm, so most men with this condition are infertile.

It's regressively sexist to suggest that males with serious medical problems are somehow female. It takes us back to the dark ages when females were basically regarded as "defective" or deficient males.
