Prepare yourself for a full onslaught of dumb:
It's fairly obvious that this audio clip, which sounds kind of like, "Islam is the light," is actually baby babbling from a cheap, one-time royalty fee sound collection. I worked with these kind of sound effects libraries in college. Why else would a baby toy and a shovelware Nintendo DS game have the exact same sound clip? The mother's Islamophobia has skewed her interpretation of an otherwise random audio recording in much the same way ghost hunters hear voices in static EVPs. This sort of auditory pareidolia is common.
But the idiocy of this utter lack of investigative reporting is not the worst of it. Implicit in this entire news segment is the notion that, somehow, a phrase like "Islam is the light" in a children's toy is inherently indecent and dangerous. Now, I'm not sure I entirely disagree, but any Muslim would be rightfully insulted.
Why am I not surprised that this newscast is from Indiana?
