I'm not sure how to articulate this well-- but I think what you're talking about are all symptoms of our society coming online, if you will. I guess I mean that both literally and figuratively in that the internet is the mechanism behind this cultural awakening. Overall and in the long term this sudden and rather jarring cultural shift will be a good thing, but right now, in the midst of it all, it seems like utter chaos. The reason I think things are different from previous cultural shifts is the speed at which ideas can be disseminated, discussed, critiqued and refined. Further there isn't a singular concise message conveniently packaged for our consumption. The old media was great at selectively informing, which made everything appear much more black and white, but now, with infinite sources of information, all the nuance is thrown at us. I would guess that this is the major source of the social growing pains that I feel like you're describing: people are still reacting as if they had the clear singular message, but the messages they're getting are fractured, nuanced, and not so easily actionable. For example, I think "microaggression" is describing a real thing which really does impact people's lives, and I think it's interesting to read about, but they also almost certainly aren't something that can be policed by social justice warriors.
