From the article:
Little wonder, then, that in this politically correct climate of intimidation, a neighbor of the San Bernardino jihadists told local media this week that he had "noticed a half-dozen Middle Eastern men in the area in recent weeks, but decided not to report anything since he did not wish to racially profile those people."
That's the CAIR effect: See something, do nothing. Silence is complicity.
Do not underestimate this enemy. They have sized up Western societal weaknesses and have implemented a strategy that uses our misplaced moral decency to hobble us. They see this more clearly than we do in our denial. They have been working on this for decades and the tree is bearing fruit. They watch us create a PC dominated culture that is slowly losing it's ability to defend itself. They laugh at this weakness and take every advantage of our own suicidal behavior.
