The problem with being encouraged to abuse freedoms, rather than being taught that freedom should be tempered by a sense of responsibility, is that it completely denies the fact that humans are still only human. Girls who aren't taught to respect themselves, because apparently self-respect is oppressive, will quickly find that no one else respects them either.
A lot of these 'proud to be a slut' sorts of arguments completely ignore or fail to understand that women should be prone to certain expectations of behaviour that men aren't prone to because we are, in fact, different.
If it's causing Western society to crumble, it's because denial of reality will tend to do that.
