if you want to avoid running into villains at any cost, it's going to be tough. if you want to avoid things having explicitely to do with the village at burning man, there are a lot of nominal gigsville events that are really just kind of l.a. gatherings.
i'd suggest, though, doing the stuff on the l.a. announce list, going to mutaytor shows, going to inge's meet&greets, paynies loft parties. there's the nuclear family, which is pretty large, has a bunch of people on the westside, and has not too much gigsville overlap. and if you can handle a crowd that's maybe half villains, you could try out santacon, and see if your fears are warranted.
or, you could announce a drinking night in venice, meet a bunch of people there (odds are i'd show up), meet a bunch of people you hit it off really well with, and only belatedly realize you fell through that door.
