You are quoting a RASHI to make the wrong point, in my opinion. If you think about what Rashi was pointing out, this had nothing to do with etiquette/halacha about who shouls preceed whom, and everything to do with Yaakov Avinu trying to protect (an act of chivalry, by the way) his wives from the possibility of being assaulted by Eisav. Eisav cared little about his women, so like Osama Bin Laden, he let them walk out first, just in case someone wanted to attack him.
