The point is, PNMs come here to ask questions and look for advice. I think we all understand that they don't completely comprehend the details of sorority life. This is why they ask the questions of the people who do know and understand what sorority life is all about.
So when they ask, and they don't fully understand the answer, or they don't hear what they want to, they ask the same question in a different way, or say "No, you don't get it." And in some cases, they provide very little detail concerning their situation, they receive answers based on those basic questions, and then they get mad because we're "judging" them. If you don't want to provide details, that's fine. But don't get mad when people answer you based on limited information.
And it doesn't just happen with PNMs. There was this thread not too long ago...

...where a new member was wondering why she wasn't bonding with her sisters. She said that she doesn't go to a lot of events, and she never goes to mixers and formals and usually makes other plans on those nights. People here gave her good advice about making an effort to hang out and go to social functions, and then she flipped out saying she couldn't because of a medical condition.
Basically, if you're looking for advice from knowledgeable people, you have to be willing to accept what they tell you... even if it's not what you want to hear. Because chances are, we're not lying to you. And if that was the case, this site probably wouldn't have lasted as long as it has.
