Derry Girls is an Irish comedy show about Catholic school. It's not the same thing as Girls.

Can you give some examples of the kinds of explanations that are still accepted in the field? Like, "Here's a trait that [some animal] has. Here's the uncontroversial scientific consensus on how it evolved."?

It seemed clear to me from context that people were comparing Singer to other affluent westerners and/or other philosophers who write about inequality. Again, not to the sort who lack disposable assets.

Singer's not posing his argument to most people, though. He's posing it to affluent people in developed countries. I think he'd agree with you that, say, a working class single mom, who sometimes has to choose between groceries and prescriptions, should not be expected to give away any wealth.

Isn't that kind of Singer's argument, though? That people who are well-off should choose to give away most of their assets in ways that benefit the poor.?
