If pessimistic: The ongoing disintegration of the interlocking sets of identities that allows democracy to function without degenerating into tribal warfare-by-other means.
If optimistic: Part of a sometimes clumsy and often painful transition from policies that assume fundamental homogeneity of values and ideas, towards a political environment that assumes a diversity of existences and prioritizes maintaining safety and moderating disputes.
If cynical: Same shit, different day.
If realistic: Yeah, what the hell WAS that anyway?
