Why is this such a big news story? I've seen two threads on this already today.
Keyes is a prominent target because he speaks straight, boldly, and without apology, or compromise in a world of where moral relativism is worshipped. Such men (and women) always have armies of detractors who despise them, who wait for the moment to attack. And when they think the moment has arrived, they attack like sharks in a feeding frenzy.
Keyes has a huge following here. Folks on other conservative sites find him an embarrassment and try to ignore him.
