True, but I don't mourn my two miscarriages now, 22 years after the fact, but I would mourn till the day I die the death of my children.
Completely subjective. I see stories of murders on my local news all the time, complete with people in the beginning of grief that will mourn the rest of their lives. But I honestly can't tell you the name of the victim in the last one of those I saw two nights ago. But my lack of grief or lack of personal knowledge regarding their personhood does not detract from my desire to see the perps get caught and have justice done upon them.
It would seem that were I to take your attitude, I would care less about whether the crimianls were ever found, since I have no emotional connection to the crime. Depth of feeling does not create objective truth, a working moral compass, just laws, or proper public policy.
