It's not healthy for anyone, for very long, but it works against unschooling.
Outrage is BIG, visceral, adrenaline-filled RAGE.
A better page for unschoolers might be Too Easily Offended?, which has a section on "outrage." But if you really did want to stick around the idea of being "outraged," here are some notes.
A phrase came along a few decades ago, on bumper stickers and t-shirts: "If you are not outraged, you're not paying attention." It would be interesting to comb out all the problems with that, but I'm just going to leave it here and let readers consider the difficulties that attitude could bring to an unschooling family. Others, too, but my focus here is unschooling.
Music is "Titans Will Rise" from composers/producers known as Gothic Storm.

The etymology (word history) is of being ultra enraged.
It was in style in the mid-19th century, when pretty much only moneyed and landed people were writing and being published. They liked to be outraged.
Then it wasn't much used, through the world wars in the 20th century. I think perhaps outrage might be a luxury of peace and plenty. When there are immediate problems, other emotions and expressions are more appropriate.
It's also possible that people are NOT more outraged, but that it's a Pokemon term, and the name of a movie, and that some of the usages picked up for statistics are not by or about outraged people.
