on definition: why terms matter

As we discuss the importance of definition, I'd like to draw your attention to two things:

1. Michelle Malkin is upset that the NY Times does not use the word "terrorist" in their story on the past week's events in Beslan. Consider the differences in definition among such terms as "terrorist," "guerillas," "fighters," and "armed captors." Why would Malkin be upset that "terrorist" is not used?
2. Take a look at this graphic outlining the frequency of use of certain terms in speech at both the Republic and and the Democratic National Conventions. In what ways do the same terms have different meanings for the different parties and their audiences?

Update: And check out this discussion at Crooked Timber on whether the media is reluctant (or not) to use the word "terrorist."
