What are the Proper Etiquette for Young Ladies?

Today, I was watching the Maury show and he was doing the paternity tests. The ladies on the show was screaming and hollering when asked questions about the baby father. Also, the ladies were talking about how the men were scum, broke, and how they have so many children by different baby mamas. Well, my question is If he's that bad, WHY DID YOU HAVE A BABY WITH THAT TYPE OF MAN? After Maury, read the results the women preceded to dance and gyrate for the audience when the results were in their favor. I just don't get it. Why not act like a Lady? Why not handle yourself with proper etiquette? Why do you need to scream to get your point across? Hey, you know there are ways of being heard without looking bad. You can get back at people without being verbal and physical abusive. For example, get in their POCKETS! Most people hate giving up money for something that can be avoided. I don't know it just bother me to see women degrading their selves. I feel like it's a reflection of me as a woman. I feel that people will think that all women behave in that manner I just feel that you can get your point across and still be a lady.
