I suppose how much you feel the interaction of the individual spheres depends on your world view, religion, etc. While I agree they aren't entirely divorced from one another I'd say that someone's bedroom proclivities has very little to do with how they function in the public world but probably much more to do with how they interact in private relationships.
Perhaps if Christian fundamentalists drew this diagram it would look more like a concentric circle diagram with all circles completely contained within the others. They frequently argue that what happens in the bedroom and private realm will destroy all of society if it doesn't fit their neat and tidy 1950's nuclear family model, whether or not that's actually biblically supported is another matter entirely.
I think most of us liberals would say that for example gay marriage would only affect society in a positive way as it would promote more tolerance of differences. We could say the same for kink acceptance as well.
Anyway, to be continued...
