Women aren't hard wired for fighting like men are. They innately follow the path of least resistance and subjugate themselves to the dominant hierarchy figure without even realizing it most of the time. Feeling comfort and protection is a woman's primary objective because it gives her the means of doing things that are intrinsically defining for a woman (i.e. finding a mate, raising a family, nurturing it, taking care of her immediate surroundings,etc.). In the face of absolute adversity, one which would require the woman to risk everything and possibly even her life, the woman would more than likely choose to side with the adversity, rather than confront it, because to confront it would require the woman to let go of her primal instincts of wanting to feel safe. World problems are for men, because we're ultimately the ones who are going to be fighting for/against it. If you want my advice, for the most part women do not want to deal with or understand these issues that will put her at risk, especially if she feels powerless, so do not hassle your wife too much with these issues. It is good to plant seeds and let her understand your viewpoints, but at the end of the day, like I said, she is quite literally not hard wired to grasp these issues or want to confront them. She will reject them and if she cannot successfully reject them she will become miserable at the idea of the "suffering that awaits." Unlike a lot of us who are ready and willing to fight the good fight when the time comes, women are not ready, and probably never will be because they've never had to be, throughout all of history. So she will not want to go there with you, regardless of how important the issue is that you raise.
