Lately I've been thinking about the general, so-called "dominant" culture as something of a disaster for interpersonal relations. It reflects many different kinds of inequality; many different kinds of "dominance." Whatever isn't dominant is less valued. For example, a lot of the self-expression we see in forums like Facebook are links to corporate material, because that gets far more social promotion than personal self-expression. Personal self-expression is less valued in and of itself; and this in turn leaves fewer opportunities within daily life in which to pursue it, to develop it as a craft. While there is certainly a value placed on personal self-expression once it reaches certain degree of sophistication, the problem for most of us has to do with getting to that point.
When personal self-expression takes a back seat to deciding whether "you" are a PC or a Mac, and relationships are formed around this basis, the end result is that we don't learn very much about each other, because we aren't referencing anything significant about ourselves. In my experience, this is just a fundamental problem of being in today's world: you can have a conversation with a total stranger yet already know the broad outlines of what they are going to say, because we're all saying the same things all of the time, whether induced by the news cycle or the rote repetition of the working day -- or by our responses to them. One reason why I've always appreciated funerals, and the "interruption" of death itself, is that it clarifies what is fundamentally important to people like a thunderbolt. No bullshit stands in the face of death -- how many things can be credited with that? The interposition of mortality into a dead routine becomes a reminder of life itself.
