All these folks posting “[x] hates [y]; still does her job” memes: do you realize humanity has executed people who “just did their job”? Could it be that you really just want a person to do their job if they agree with your beliefs, but want them to abstain when they disagree? You are vilifying a practice that you need to have available when someone asks you to perform a service which you have a moral objection to.
“We need you to dump this poison into the water.” “I have a moral objection to that.” “Just do your job.”
…or: “We need you to collect this metadata on American citizens.”
“I have a moral objection to this.”
“Just do your job.”
Now, we should totally be having a discussion on whether or not we agree with this person’s morals, but the idea (generally) of conscientious objection should never be questioned.
