why is phi sig being so mean?

I thought that Phi Sig was nice and friendly to all orgs since they're new and want to be accepted as a legitimate sorority at JMU but boy was I wrong. Any ranking post that has Phi Sig above AST, GPhi, or ADPi is a self rank by a Phi Sig. Then people try to correct them saying they're all equal to which a Phi Sig replies to quickly since they live on this site and make some nasty comment about one or all of these sororities and says how great they are. I THOUGHT maybe not all Phi Sigs were like that when I saw someone comment on a post like stop saying these things Phi Sig loves GPhi! And I thought that was really nice UNTIL a Phi Sig comments saying that a Phi Sig would never say that and it "must be" a GPhi girl "spreading lies." ummmmmm Do you really think that makes you look good or cool or better than another org by saying you would NEVER say you like them. I don't understand how a sorority who hates all other sororities would be appealing to a PNM. Interesting recruitment strategy ladies. Sorry you can't handle that you're equal to a few other organizations and feel the need to shjt on them just because others agree.
