Trans are caused by chemicals like atrazine in the parents and in utero, from the food, water, and environment. It causes opposite gender gene expression, which can lower testosterone or estrogen and other gender hormones. This causes a feeling of dysphoria known as gender dysphoria. Instead of getting them the psychological and medical help they need they are told they are in the wrong body, given drugs that destroy their body and destructive surgeries. Most regret it later in life and try to transition back.
It's sad really and abusive.
