Psychology teaches us that when failed behavior, behavior which is being extinguished, which does not succeed and is not rewarded, there is usually a large final burst of that activity before someone gives up. The more adaptive, the more brief that final burst; the more angry and frustrated and mal-adaptive or incapable of change, the longer that final burst of activity before it stops.
This is that kind of tone-deaf, angry, intransigent gun-culture failure. Conservatives are, sadly for us and for them, consistently on the wrong side of history on every issue. This is just one more.
Badly done, Senator McCain; wrong - AGAIN.
