This is becoming a bigger and bigger issue, particularly in the tech industry where trendy is everything.
People would be rightly shocked if a job description for a high-tech position said: "whites and South Asians only" or "women need not apply." They'd be shocked not because racism and sexism aren't rampant in these firms, but because the company would be explicitly acknowledging that the racism and the sexism exists. However, whilst they're sensitive about being outwardly racist and sexist, high tech firms are total fine with discriminating against one type of job candidate: anyone born before 1985.
Quite possibly the real reason that non-existent racism and sexism have been focused on to such an extreme extent by the media in the past couple years is to distract from the white elephant in the room: AGE DISCRIMINATION!
