Do you have an example where “more perspective just means witnessing more atrocities”?

I spend a couple of hours a day in the NICU as a new father. It's an experience I've never had before, so I'm learning what it means to be a parent.

Recently, one of the women who I'd seen at the bed next to mine on a daily basis for months stopped showing up. Her baby was attended to by a nurse.

I find out from one of the staff that the mom was flagged for intoxicants in her system at birth. She was reported to CPS. They had come into the NICU while she was feeding the baby the prior day and the CPS official had pulled her out of the room, scolded her for being an addict, and forbad her from reentering to see her child. She was then removed from the building by security, screaming and crying.

This story is tragic as told. But as a new father, it carries a much more rarified horror.

There’s definitely an argument for limiting "doom and gloom news for ones own mental health…

This isn't simply "the news". It's a certain consciousness of the world around you that you develop through lived experience.
