I don't know if propaganda is too strong a word - but I personally am disturbed by it's message.
I felt like I was being told that the MOST important thing in the world is to hold on to your first love. Even if he's a possesive stalker. It's okay the Edward shoves Bella around a bit, he's doing it for her own good. And New Moon, when she was catatonic for however long, that's also okay girls - if your boys leave you, you should become depressed up until the point at which you throw yourself over a cliff because without a man in your life: because without him you are nothing. Bella not going to college bothers me too - it seems as though her only goal in life is to love Edward and to serve him. All the girl does is cook, fall over and need saving. How is she a positive role model?
That's just my interpretation, I'm sure many girls found Bella empowering (how exactly I'd like to know.) If I had a teenage daughter, I would never stop her from reading any book, but before she read Twilight she would recieve a long lecture on how the most important things in life are not her virginity, serving men or obsessive love.
