Liza Talusan blogs about a negative experience a friend had when his "Got Privilege?" shirt offended a white person:
Recognizing privilege, owning up to your privilege and then actively identifying ways in which we institutionally disempower those without privilege gives us tools in our toolbox. It helps us to call attention to ways in which we play into systems of oppression. It awakens our sense of responsibility and turns on the voice in our hearts to call for change.
