I'm actually going to disagree on this one, Addy.
They made the movie, which does a tremendous amount to shed light on the subject. They took on tough, risky roles that will ultimately do an enormous amount to raise awareness and change minds. They've been talking about the issues constantly in interviews, before and since the awards. This, however, was an awards night, doling out awards to actors for their work. I have no problem with them having this moment be about them...because it is!
I think there's a trend recently for the press to pounce on good people over a slight misstep. I think this is dangerous in that it makes people afraid to put themselves out there for issues they don't need to worry about for themselves. They do it because they care. But they might stop if we keep slapping them down for not doing it in exactly the correct way.
Art has a double face, of expression and illusion.
