let me add a thing:As I am reading this, I am thinking of those cultures today, as well as in the past, where women are trained to see that this is a man's world, and the proper role of women is to be of service to their husband, which in strongly patriarchal societies is closer to 'owner', than a soul mate in the sense we think of as modern romantics. So training of women at an early age, to understand what their duties are to be when they mature, is simple par for the course.
Even today in our modern Western societies, women are programmed from early ages on to fit into this 'man's world,' when they are raised in traditionalist, conservative homes. That is the world they inherited, they were taught to support, and then pass it on to their children the same was it was programmed into them. It is seen as their duty to do that in support of their society.
But I think here, you are looking at this from the postmodernist perspective, of equal rights of women, elevating individual rights over prescribe roles. These are different worldviews, different realities.
The funny thing is, what they are calling a culture war, is in reality, a worldview clash. They can't understand not telling that young girl what will be expected of her as a woman, and we can't understand why they hell they would. It's entirely different realities.
Asking intrusive questions, even sexually explicit ones, to children aged 11-15 like the Mormons do (see #37)... only educates them to be open to infringements on their pesonality sphere.
When an authority person wants to rape them, which is also an infringement on their personality rights, they are already used to it, I'm afraid.
It would call it a culture of sexual harrassment.
But as a commenter in the comment section of said video pointed out, this is not limited to LDS churches, it might be a much broader issue as you say.
