I'm not sure that I disagree with this. I'm a Christian, so I have a particular set of beliefs which I base my life around, but when I was nursing, I had to leave those beliefs at the door. I wasn't allowed to share those beliefs with my patients (unless they were specifically asking me to, e.g. if a Christian patient asked if I believed, I would say I did). I am gender critical, but I wouldn't share that belief with a patient.
As a prospective police officer, I wouldn't share my privately held beliefs. So unless there was a question such as 'do you believe that TWAW?' it shouldn't come up during the process.
