political divide among greek houses?

Okay is it just me or are the orgs kinda separated by political affiliation? With the guys, Kappa Sigma is the conservative one and Sigma Tau is more liberal, but KSig is the more extreme of the two. And then for the ladies, Gamma Phi is conservative and Delta Zeta is liberal, but Delta Zeta is more extreme. Does anyone else think the orgs are split politically?
