We've talked on GC about forced prefs. These days, prefs are rarely forced but the PNMs have that carrot of QAs if they maximize their options. Still, I think that many, many girls are going to some pref parties unwillingly and that could account for the flood of 'rude PNM' stories that we've gotten on the Weird Rush Stories thread (maybe if I flip off the undesirable group, they'll cut me!")
