I think that's a gross oversimplification of what's happening here. I mean sure, you can go along and say that only shallow teens do things like that, and only shallow people are insecure in their opinions, and only young people act out the social dynamics that were drilled into them from the word go.

You can focus on the fishing compliments people, and Ignore the very real social pressures that are put on women, and that women put on themselves. You can pretend the harsh lessons we all learn in high school don't follow us into our adult lives, and you can ignore the fucked up parts of society and be blind to how it effects you directly, and not those other silly, shallow, insecure teenage girls who don't really matter anyway. You can blame those things on modern life, and pretend things like this are a new phenomenon.

I wouldn't personally recommend it though....
