Should expressions of Christian belief be career-ending?

Should expressions of Christian belief, spoken anywhere vaguely outside of our own bathrooms or anywhere else where nobody else will hear them, be career-ending?
That is, unfortunately, no longer a theoretical question in the UK. Read here to find some of the extracted arguments of the lawyer of Sheffield University - a university, still thought of by many as a bastion of free thought and inquiry - arguing that such expressions should be automatically career ending, across a whole swathe of careers. The lawyer was arguing that such expressions in this case justified expelling a student from a course related to social work, on the grounds that said student had disqualified himself from such a career by expressing Christian thoughts on Facebook.
