Arguing that the money is better spent on young people, smart people, cancer research, or whatever as opposed to comatose people isnt materialistic. It may be wrong but it isnt inherently evil nor based on “Dark and evil places”
Arguing to save the lives of young people before older people, most certainly is inherently evil and based on dark and evil impulses.
How do you dare argue otherwise, even as a possibility? Do you forward the same argument about saving white people before black people as you do about young people versus older people? After all, white people tend to live longer than blacks, lead more productive and wealthy lives and contribute more to charity and culture.
