LOL........See your point but don't it also depend on where your standing in relationship to the grenade?
The fear and paranoia are the reasons for the grenade. The more fear there is, the better the odds of finding your relationship closer to the grenade.

I know of plenty of paramilitary survivalists, and Christian religious fanatics accumulating that stuff (think Waco) who have nothing to do with Muslims, Jihad, or Islam. (well, now they do because they have some other excuse to be afraid, and another obsession to fret over.)
