We can ignore human misery, so long as it is happening to other people.
In the news business, there is an old saying that a murder in your town is a headline, but a murder in another town isn't. Maybe two or three people killed in another town is a headline, or a dozen in another State, or a hundred in another country, and so on. We care less and less, the more removed the incident is from us.
For example, there was a recent suicide bombing in Kabul. What a tragedy - 100 people killed, 18 of them Americans. But if all 100 were Afghans, well, the outrage would be a lot less. We identify with our own. It is like the Olympics - the press reports a big story when a US Athlete or team wins, but doesn't say much about Romania winning the gold in synchronized swimming.
It is, perhaps, human nature. And human nature is not a very pretty thing - it is derived from our animal nature, and that gets pretty ugly.
The new variants of the Corona Virus are once again driving up the death and infection rates. It is not yet at the peak we saw earlier this year, but it was starting to look like the whole virus thing was gone, and now it is resurgent. And many, if not most, of those infected, sick, and dying, are people who refused to get vaccinated.
I have two observations on this. First, when we go to a gay campground, the inoculation rate is 100%. Most people who lived through the AIDS crises don't think twice about it. After all, if there was a vaccine for HIV, people would have lined up around the block for it!
