Your point is well taken. I've had conversations with people on tidbits of information I've received from those with "boots on the ground". Some people listen intently and seem to understand. Others? It would take a 2000 pound bomb going off in front of their own home to wake them up to the dangers this world faces from these terrorists.
Others?
Some people insist on living in a very very small world, and there's nothing you can do about them. Well you can hit them on the head with a ballpeen hammer, but the police tend to take a dim view of that sort of thing.
No it wouldn't, because these type of people do not comphrehend what terrorist really want. They wilfully ignor who terrorist really are because that would bring their world view crumbling down.
This is a spiritual war that will last until every last one of these terrorist are either dead or converted.
That's what scares them so bad because they know it true.
