You are incorrect. It would be like claiming diabetes is a mental illness; both are the result of a defective endocrine system.
People who choose to remain ignorant of the causes of gender dysphoria are ill-prepared to fight in the trans wars.
And a defective endocrine system - along with serious hormone imbalances it causes, affects the mind as much as it does the body - making one mentally ill. And they try to “fix” it by creating even worse hormone imbalances.
How do you see yourself as “prepared to fight in the trans wars”? And what does that even mean?
