Do you have any fear or concern for the growing multitude of radical Islamic extremists that threaten us?

These people teach their children from birth to hate or kill non-Muslims by any means including suicide bombings and believe that this will hasten the coming of their paradise. Doesn't this religious fanaticism which could manifest itself in bombings at the mall or a sports event or your kid's school concern or scare you?...and please...no sarcastic remarks about Christian radicals threatening your right to view in America or some such nonsense such as a Christian president being scarier...
