Amish Airline Hijackers?

Some people hold to a a very ridiculous notion: that it's dangerous to believe something too strongly.

This is so silly! First of all, if this assertion is true, then the person who holds this position is dangerous. Why? Because if this person strongly believes that strongly believing is dangerous, then he (or she) is the dangerous person he is worried about. Look in the mirror, Joe!

But some people (I especially heard this right after 9/11) put a finer point on the argument. They say that strong religious belief is dangerous.

Well... it's still silly.

For example, Al Qaeda strongly believes it is right to kill people (at least if they're Americans), and the Amish strongly believe it is wrong to kill people. So, will anybody seriously suggest the Amish are as dangerous as Al Qaeda?

It's what you believe that's crucial. How strongly you believe it is secondary.
