I'd absolutely buy that there are regional variations in how common those phrases are. The map appears to be spot on in that sense based on my own experience.

I'd absolutely buy that there are regional variations in how common those phrases are. The map appears to be spot on in that sense based on my own experience. I'm just wondering if there are areas where "you guys" can't be used to refer to arbitrary-gender-makeup groups (as opposed to areas where it's just less common than other phrases accomplishing the same purpose). I haven't personally encountered such an area, but I accept and acknowledge that you have. I do think this topic is complicated by the ease of conflating current usage (how is "you guys" used today?) with ideal usage (is this really a phrase whose usage we want to promote and accept in the future?). I personally have no problem making an effort to phase out "you guys." It's not something I feel attached to, and I can see that it carries unnecessary baggage.
