What's Her Purpose?

As I read My Colombian War, I struggle to identify what is Paternostro's real purpose in writing the memoir. She definitely has a strong opinion about politics and violence. Paternostro also has an interesting personal perspective, as an upper class Colombian rediscovering her roots. Her writing is good--she keeps it interesting and manages well her polyphony, as she talks about her life as a child, her life in New York, her trip to Colombia and other relevant stories. But what is her point in writing all this? At first I thought it was to criticize the Colombian aristocracy and back up the communist rebels. I also considered it might be just to narrate how it's like to be a journalist. With a lot of potential in her memoir, I believe she settled with simply complaining. It might be that she wanted to keep the juicy stuff for later in the book, but so far all the author has done is complain.
Silvana Paternostro complains about the violence in Colombia, the negligence its citizens give to it, the poverty in the country, the lack of education, basically, she is dissatisfied with the country as a whole. It's a valid point to criticize the inequality in the country, or to try to make a point in that Colombians should act upon their situation, but she doesn't do either thoroughly. Paternostro protests that Colombians don't care about their armed conflict unless the guerrillas are on their "finca's living rooms." Nevertheless, she only states that she dislikes that. She could try to use her book to convince people to do something, but she doesn't. In another point, the author suggests that she dislikes that women sit in the back of the cars when with their drivers, and that her driver didn't want to join her in the museum visit. Again, as an author and journalist, she could try to make a point, but she doesn't. Instead of appealing to logos and giving arguments for people to do what she thinks is right, but she only seems to be using wrongly pathos for her rhetoric, talking about how eager she is to go to her finca at El Carmen. I think that Paternostro has really good material for a detailed and informed social critique, but so far, I've only read complaints. I'll keep waiting for her ideas to actually form an opinion or analysis. Although I believe the memoir lacks that component, it is still interesting to read her book, since, like I said before, she has interesting stories about Colombia that are worth reading.
