That is a deceptively simple question. These tragedies are opportunities for people to broadcast their allegiances, their politics, and, really, themselves. And that can be frustrating to witness, especially if you come from "the other side of the aisle." But I take solace in the fact that by rubbing up against one another, we learn a thing or two. That said, it's heartbreaking how rote some of my reactions feel to this tragedy. Yet, I don't think that's what you mean when you say there ought to be no discussion. It's not that we've been habitualized and desensitized to this (though to some extent, we have been), but that these freak occurrences are part and parcel of a large, heterogeneous society. So what am I supposed to do with all these hurt thoughts?Where's the discussion?
