"At the heart of the problem is confusion over the nature of the transgendered. “Sex change” is biologically impossible. People who undergo sex-reassignment surgery do not change from men to women or vice versa. Rather, they become feminized men or masculinized women. Claiming that this is civil-rights matter and encouraging surgical intervention is in reality to collaborate with and promote a mental disorder."
