why all the hate?

I'm very confused, because for a group of ladies who are all about sisterhood, I'm finding a lot of animosity betweenn the different sisterhoods. Yes, they all have different characteristics and different tastes, but you all have one thing in common: sisterhood. Shouldn't that mean something? Obviously, you should be proud of your sisterhood. It is something to be proud of, but putting another sisterhood down is just a little dumb. I mean, who are you to judge how a sisterhood functions. In real life, there are some sisters who never speak to one another, there are some who only go out partying all the time, there are some that go do community service together. I don't think you can rank the way we choose to behave, interact and care about one another, because each person, each sisterhood is different. Just because you don't understand something doesn't mean you should hate on it... I also understand that this website blows it out of proportion, but still...
