No. I think you're the one missing the point. Everyone gets all high & mighty in the Rush threads and tells PNM's that they should always walk in with an open mind & not judge a sorority until they've gotten to know them. Now you're telling this girl that it's o.k. to want to leave her GLO b/c she doesn't want to be in the "loser" sorority? Ummm...yeah. That makes perfect sense. Go into rush with an open mind but feel free to depledge w/out giving it a chance b/c someone else thinks you are in the "loser" sorority.
If she wants to quit it's perfectly fine especially if she's unhappy w/her current situation but don't you find it hypocritical to tell PNM's to have an open mind then turn around and tell a NM to drop if she doesn't want to be labeled a "loser" along w/her GLO.
