re this:
"It strikes me that the North American anarchist movement might..."
i would strongly suggest that you don't go down that road. POC have their own thing going on. it's called APOC, and as far as i can tell from the outside, it's a true representation of the state of most anarchist thinking about race, which is to say, not that great. (i'm assuming that's because it's harder to theorize well about experience than it is to experience it, although i guess that's a false dichotomy too. sigh.)
My Point is that a) we all have a ton to get out of a more nuanced and good analysis of race (and identity of all sorts), and b) to start out with trying to make one's analysis fit into a model of recruiting is to cut off the feet of something that can't even walk yet.
there's plenty of critical race theory that is crap. but the most interesting theory on race that i've read in the past 5-6 years (not that i've entirely kept up, perhaps) has been some of the CRT thinkers. the ones that drive me crazy are just taking a more sophisticated perspective on essentialism. the ones i like (derrick bell, lisa ikemoto, anita allen's piece on being a role model) challenge essentialism and/or other presumptions that most take for granted in the race discussion.
