MAGA morons have consistently argued against extending aid or sacrificing our resources to help people outside the United States.
I've said repeatedly that scientific Darwinian evolution encourages cooperation within the kin-group, tribe, or social group. But not extend it to outsiders, non-kin, or rivals.
There is nothing about biology, Darwinian evolution, physics, or chemistry that encourages you to sacrifice your resources to help outsiders, non-kin, or competitors.
The kind of self-sacrificing universal love we're imagining is a religious or spiritual value, not an ironclad law of science.
