Why does everyone think that Muslims are terrorist?

It seems like a trivializing term for something so terrible, but terrorism is something of a fan among Muslims. This is not to say the it's universally adopted by them, nor that no other group uses it; however, whereas when Irish thugs kill old men and children, as the IRA did in the bombing of Lord Mountbatten's yacht, or a renegade group of Amish start attacking their political adversaries, there is prompt and widespread condemnation from members of the terrorists' own societies, in Islamic countries, terrorists are often looked upon as heroes: governments pay their families huge bonuses; mothers name their newborns after them; the pictures are displayed in parades and their suicide tapes are endlessly replayed. Just as negative stereotypes in the West (drug dealers, pimps, con men) are embraced by some minorities, the idea of being a terrorist (which they call a "martyr") is attractive to many Muslims who see it as a path to revenge for Western slights real and imagined, glory and fame, and, of course, the various sensual delights promised by Mohammed for those in martyrs' paradise.
