"She also made reference to the fact that she would always personally object to participating in “killing” an unborn child."
As an atheist who is pro-choice, I dislike the emotive, morally-judgemental use of the word "killing" here. However, I fully understand why someone who is pro-life for religious reasons might use this word even though lots of US religious pro-lifers are also pro-capital punishment and the right to bear arms etc to express their belief in this way, in addition to simply saying that they are pro-life.
I wouldn't expect her to be suspended for saying any of this though. Especially as she went on to qualify that "she would never impose her “morals” on women in her care"
However, if they think she should be, to be consistent, they also need to suspend Dr Upton.
Dr Upton stated a belief that "I am a biological female" and then went on to describe a situation where this belief means it's fine to deliver same-sex care if a female patient has asked for a female doctor.
If the nurse can be suspended on the grounds of fitness to practice for commenting on a theoretical situation relating to her belief, Dr Upton should be as well. Especially as Dr Upton stated a clear intent to impose a personal belief on a patient.
