"One way to think about a pure hyperbolic surface is that it's the geometric opposite of a sphere. If you look at a sphere, the curvature is the same everywhere, as opposed to, say, an egg, which clearly does not curve the same everywhere. This is what makes spheres geometrically important. Mathematically speaking, a sphere has positive curvature and a hyperbolic surface has negative curvature, but both have constant curvature everywhere."

Of course, I could never suggest that only poor people are misogynistic; too many rich folk are just as hateful of women as any poor person might be. I don't know if social problems are only circular; perhaps other geometric metaphors might better describe the triangular effects of social vulnerability, political oppression, and racial disadvantage. I think you're right - we've got to focus on both analyses and solutions. And sometimes, an adequate analysis goes far along in suggesting a suitable solution.
