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.

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.

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.
