I know that you can’t judge a society by its worst members. And you sure as hell can’t guarantee that just because you liked a book, movie or TV show that everybody else who liked it will be as tolerant as you.

So why does it hurt so much that a group of racist idiots are ranting about the casting of black actors in the movie version of “The Hunger Games?”

The story broke wide on the website Jezebel. Under the headline “Racist Hunger Games Fans Are Very Disappointed,” writer Dodai Stewart notes that a tumblr, “Hunger Games Tweets,” collected Twitter comments about the movie and snared a few that were, to put it mildly, racist.

I’ll only quote a couple here.

“why does rue have to be black not gonna lie kinda ruined the movie,” one idiot pecked out.

“why is rue a little black girl? Stick to the book DUDE” is another.

Let’s put aside the fact that author Suzanne Collins, in describing Rue and fellow District 11 tribute Thresh, notes they have dark brown skin.

Let’s put aside that the DUDES who made “The Hunger Games” movie stuck to the book. DUDE.

Why would it matter how the characters were cast? Doesn’t some diversity in casting — and in creating the characters of Collins’ original novel — enhance believability? Otherwise, are we supposed to assume there are no black people in the future?

Maybe that’s the Twitter writers’ fantasy, but it’s plainly not Collins’ and it’s not mine. Or most of us, hopefully.

Time for one last tweet:

“Kk call me racist but when i found out rue was black her death wasn’t as sad #ihatemyself” one person wrote.

Two things to note about that tweet:

We hate you too.

And you left off the third “K” at the beginning of your Tweet. DUDE.
