When you say something is wrong and something must be done there will always be those who say "talk is cheap." Ask these people what they would have of you: do they want you to act, as they pretend they want? Or do they really want you just to shut up? And ask them what they themselves are doing about the injustice. Are they speaking out against it? Acting against it? Both? Neither? Usually it is neither. Those who decry those who decry injustice are almost always not the bold fighters against it, but its defendants.
And if talk is cheap, why do the rich insist on owning the media?
