Shocking that people could somehow miss that Rue, Thresh, Rue's family (in the sequels) etc, are absolutely intended to be black. Cinna is, as the article noted, not described in a way that indicates what his race might be. But Rue and Thresh were unambiguous (kind of wish Thresh's role had been bigger, though). I can only assume that these jerks ignored all of those descriptions (though I don't konw how) and focused solely on the fact that Rue reminded Katniss of Prim. But it takes willful denial to have ignored Rue's and Thresh's race.

Those tweets are shocking. (and claiming this "ruined" things for these readers. WTF?!!!!) It would have undermined the story if they hadn't been!
