yeah-- those damn details... always an annoying part of any argument. Also, I like how you imply that you can't both understand the "big picture" and care about the details. To me, it seems like the only way to understand anything. If you aren't conversant with the details of what you think, do you really understand what you're talking about?
Perhaps an important detail, then: Thatcher's quote was actually "And, you know, there is no such thing as society. There are individual men and women, and there are families."
... as if families, themselves, weren't each a kind of small society.
