Individualism, Social Justice, and Boundaries

Is there an intrinsic tension between upholding concern for others through social justice causes and the insistent maintenance of an individualistic mindset, especially one manifested through the assertion of personal identity that is apathetic to the reaction of the other?

Can one insist that people should care about a certain cause while simultaneously insisting that one can do what one wants, when one wants, how one wants?

Or perhaps concern for others ultimately comes at a price to pure individuality, to the notion that we are atoms randomly bouncing into each other. Perhaps concern for others ultimately means that boundaries, while necessary, are not "dogmas" and that a boundary must serve a person and not vice versa.
