Yes, my point in saying “cured” is that it is a loaded statement but is logically consistent with the idea being trans is inflicted upon you by something external, and that would lead to conversion therapy which has been shown to not work.
There does need to be more research. The current research supports what I’ve said, and future research could change that. However, at the very least some people are born trans, even if others somehow become trans in some critical early developmental milestone.
As for the idea that the research is seeking evidence of transness being inherit at birth: that is not the case, there have been many attempts to study so called “sudden onset gender dysphoria” or the idea that someone could suddenly become trans, and those studies can’t find any evidence for that (other than one that asked TERF parents if it seemed sudden to them, who of course said yes). Other studies have shown that people tend to have a concept of their internal gender from about as soon as they can talk, which is the earliest we could possibly test, indicating that if it is not prenatal then very early in life.
Yup. My belief is that we are likely to eventually combine the categories of transgender and differences in sexual development (formerly known as intersex) as we discover more about it’s biological origins. The vast majority of people have never been karyotype and have no idea what their chromosomes are.
