It Seems More and More Pointless

You know, people have been telling me that there are different kinds of Muslims, and even amongst themselves they don't get along, but I don't think that anything has ever really made it this clear to me before:

Suicide bombers kill 77 in Iraq

Isn't bombing a place of worship a really cowardly and hateful thing to do? That's my impression, at least.
