I'm sure most of them don't see themselves as selfish.
I chalk a lot of the attitude up to two factors, depending on the person:
- denialism. They dispute the basic facts about the disease. They consider themselves low risk because they see the disease as low-risk generally... i.e. that the impact of the disease has been misrepresented (or even is an outright lie).
- innumeracy. They accept the facts of the disease, like the death toll and number of cases, but don't understand how to draw valid conclusions about their own level of risk - or the risk they pose to others - from this information.
Based on her posts, I'd probably put
@Unveiled Artist in the second category. Other members here... they vary, IMO.
