rancorous
Rancorous: characterized by bitterness or resentment. The word “rancorous” comes from Middle English rancour, Old French rencor, and Late Latin rancor, derived from Latin rancēre, meaning “to stink.” Over time, its meaning shifted from “rottenness” to “bitterness or resentment.” I believe it is used correctly here as the authors are portraying the harsh divisions between Capitalism and Communism.
There is no path tobuilding transformative solidarity that bypasses the construction and deployment of identity
Here Taylor and Hunt-Hendrix argue against the idea that identities must be thrown off to promote solidarity and that ,on the contrary, inclusion of various identities is the only way to build transformative solidarity and to overcome entrenched divisions.
But if change is our goal, we must understand how collective identitiesare constructed beyond the basic categories of ethnicity or nationality, and how thatconstruction can reshape the world around us. Transformative solidarity is abstracted from ourgiven identities and extended outward to create wider circles of belonging
It seems that transformative solidarity is centered not on necessarily changing the "Us" but reframing it. In order to bring change we must take the solidarity we feel from friends and family and expand those feelings to broader societal categories. In doing so we practice transformative solidarity and create more uniformed collective identities.
