On p. 27-8 of my copy:
To say that whiteness is a standpoint is to say that a significant aspect of white identity is to see oneself as an individual, outside or innocent of race – “just human.”
This standpoint views white people and their interests as central to, and representative of, humanity. Whites also produce and reinforce the dominant narratives of society – such as individualism and meritocracy – and use these narratives to explain the positions of other racial groups. These narratives allow us to congratulate ourselves on our success within the institutions of society and blame others for their lack of success.
To say that that whiteness includes a set of cultural practices that are not recognized by white people is to understand racism as a network of norms and actions that consistently create advantage for whites and disadvantage for people of color.
These norms and actions include basic rights and benefits of the doubt, purportedly granted to all but which are actually only consistently afforded to white people. The dimensions of racism benefiting white people are usually invisible to whites. We are unaware of, or do not acknowledge, the meaning of race and its impact on our own lives. Thus we do not recognize or admit to white privilege and the norms that produce and maintain it.
It follows that to name whiteness, much less suggest that it has meaning and grants unearned advantage, will be deeply disconcerting and destabilizing, thus triggering the protective responses of white fragility.
