None dare call it mental illness.
Actually the medical profession did call it a mental illness up until the ‘70s. That is when the left came in with their notions to “de-stigmatize” mental illness.
“I think the expansion of the power of LGBT political and sexual activists, along with political correctness, has moved the cause of civil rights for transgenders beyond what anyone could ever have imagined.
In my view this “frontier” ignores the greater need to provide effective and sound diagnosis for transgenders. It is politically incorrect to point out the science that shows transgenders suffer from undiagnosed co-morbid disorders that cause the desire to change genders. The lack of effective diagnosis and treatment of co-existing disorders in transgenders, evidenced by the high rate of suicide attempts, is covered up by the call for civil rights. The politicizing of a medical issue has hindered research and thereby harmed those who suffer from gender dysphoria.”
