I should start by saying that, as far as I can tell, Rajchman gives an excellent explication of Deleuze's theories. When Rajchman uses a piece of Deleuzean terminology without explaining it, he's using a milder form of the obnoxious rhetorical strategy that Deleuze himself employed, but it's far more readable in this context.
It's been a long, long time since I was 21 or so and read a great many of the works of Gilles Deleuze and was amazed. Now that I'm revisiting Deleuze's ideas a bit more sober, a bit more adult, and while I find them no less provocative, I'm more and more aware that they are an untenable basis for any real program of political or social change. Now, Deleuze may have argued that his ideas should stand on their own merit, without any intent towards changing the world. If that's the case, then, why does he always get lumped in with the world of French militant philosophy? They're still brilliant ideas, but they fail to form a basis for a systematic "practical philosophy" that Deleuze was so insistent on moving towards. Rather, we get an onslaught of concepts-- multiplicity, rhizome, etc.-- that may provoke us towards some interesting ideas, but are signposts as opposed to actual arguments.
