are chapters really so different?

I'm so confused by the intense dislike/hate I'm seeing on here (depending on the org, not just "low tier"). Personally, my most genuine interactions were in Pi Phi, but I know that could just be I was luckily matched with the perfect person for my personality. Why do they get so much hate here? ZTA and AEPhi also made me feel very welcome and like they were interested in me as a person. I enjoyed the others in different ways and think I could make friends in them all. I just don't buy the ranking going on here and wish everyone would calm down and worry about their own process without trying to influence others. What good does it do? All of the chapters seem to have many great attributes. This site is not a good look for NYU.
