"To fight the hysteria and stigmatization of people who care for Ebola sufferers but do not themselves show any signs of the disease."
But then why would she avoid contact with others? I was responding to your contention that her breaking quarantine is only "symbolic".
Either quarantine is prudent or it isn't. Doesn't make sense to say one thing and do another.
"If you demonize people like this nurse, you discourage caregivers from going to West Africa to fight the disease. Is that a good idea, in your opinion?"
Her going to West Africa is not what I've had a problem with. I don't like her behavior since coming back.
So yeah, if people who interact with ebola patients can't be considerate of their neighbors when they come back then I'd say they shouldn't go.
