But to @JardyB10 @Berocka @Gaikoku-hito and anyone else, I read this article yesterday (beware, it's a beast) which delves a lot deeper into the culture of outrage etc and does a very good job. It's got an American lens to it and from this side of the pond it does seem a lot more extreme over there but covers social media which is more international quite well.
