Zizek's defense for thinking the right thing

When Zizek speaks, you'd better listen carefully. Joking, :)

Here is his latest essay on an old subject, that is, whether action is more important than thinking. The essay is written at the moment that Barak Obama, the democratic presidential candidate, seems to be facing some problems on his rhetoric of 'audacity to hope', as 'to hope for what', or 'to change what?' have become looming concerns among some swing voters.

'Our global situation is not only a hard reality, it is also defined by ideological contours. In other words, it’s defined by what is sayable and unsayable, or what is visible and invisible.'

I remember he once said that writing itself is an act, but he didn't elaborate in such a manner, so it seems to me he has implicitly endorsed Obamas's rhetoric because he says what is unsayable and invisible, that is,

'the continuing importance of race in politics, the positive role of atheists in public life, the necessity to talk with “enemies” like Iran.'

Zizek argues that US politics needs new words to change people's mind and way of thinking, with the general consensus that change is badly needed in US. Probably McCain's rhetoric can be seen from such a perspective, and who will win finally will indicate whether the majority of American voters are aware of such a need.
