Zizek’s latest Guardian piece seems more disjointed and confusing to me than the last one. What he seems to be saying is essentially that if liberals exclude the radical left, they will be unable to resist radical Islam — hence the radical left makes the world safe for liberalism? That seems like a weird argument to be making.
I also expect that those who customarily critique Zizek will point out the apparent contradiction between his opposition between the radical left and radical Islam and his use of Christianity, etc. Yet to me that critique misses the point of his work on Christianity and also ignores the fact that he has also claimed that there is revolutionary potential in Islam (as in his piece on Iran from a couple years ago).
