They are still a very primitive society, so it's very deep-rooted. It took us centuries to progress to where we are today, and the difficulty is bringing other cultures up to that level asap - very difficult. And we're still far from perfect ourselves - e.g. IRA atrocities, Paedophile Rings, Fox Hunters, all pretty primitive activities.
The misogyny shown by this example is also around in some areas of our own culture, albeit not so deadly in execution.
Like Talbot, I don't know the answer, but I don't believe it's bombing them, or persecuting them in any other way - that tends to drive them to close ranks and become more stubborn.
