I don’t agree that this is right but I think it goes like so:
Men are expected to die. Younger women dying means less babies. Children dying means less future / could have been your kids. Older women dying means that could have been your mom / grandma.
This applies to US News and all named peoples expected to be white with Euro-American names.
Different rules apply to PoC and/or non-Euro-Americans. That often does not get standard media coverage, sadly.
