Why do u care so much about self rankings

Ok ppl here is what I’m seeing on this site is the constant accusations of “oh so and so chapter is self ranking” but why in the actual F do u care? I HOPE every girl thinks her sorority is top tier and loves her sisters enough to post ++++ about them. If ur chapter is so great then it shouldn’t be an issue IMO???? Don’t be so Fing threatened by a RANK to talk cr@p about another chapter when you can’t possibly know if you ain’t in it!! GTFO
