As I pointed out, it is not simply a job, but a profession that the state regulates. We do not want a society in which the state bars Christians, observant Jews, and others with stricter moral beliefs than the anything goes as long as the adults consent ethics of secular humanism from holding lucrative state-licensed professions.
Only those willing to perform abortions will get licenses to practice medicine, only those willing to dispense abortifacients get licenses to be pharmacists, only those willing to support judicial activism can be lawyers, only those willing to peddle the party line can be school teachers, any psychologist who treats a dissatisfied homosexual looses his or her license. . .
Exclusion of pious Christians and observant Jews from the professions is a secularist analog of the tactics of Islamic regimes in which perks are available only to Muslims, and should be opposed with the same vigor.
An employer should be able to fire folks who won't perform their jobs. The pious Christian pharmacist can find work from an employer who will either hire another pharmacist on the same shift so the conflice arises, or from a pious Christian pharmacy owner, or can set up his or her own business. The state should not enforce immoral behavior as a condition for professional licensure.
"so the conflice arises "
should have been "so the conflict does not arise"
