My ultra-conservative son said the same thing - - 'Crash' is not an overly judgmental film, nor is it accusatory , overbearing, politically correct, or in-your-face in any way. He says it's a flat-out great movie.
I think the Academy got it right.
Let the, "Oh that'th thimply ridiculeth", wails of the sodomy community begin.
Your son is right.
