Here is an idea we can all rally around:
This idea is not original, but at the moment I can’t find where I saw it. We need to take back the word ‘martyr’. When a suicide bomber blows himself and 10 kids up on a bus, the ten kids are the martyrs not the crazy bomber. When an Iraqi voter gets killed for walking out of the polling place–he is a martyr for democracy. (I think that was the case I originally saw). We should avoid martyr status for evil people.
Of course, this is of little practical value unless those who are currently in the habit of engaging in suicide-bombing adopt it, but it is a good idea nonetheless.
