Here are a pair of good posts about the overuse of the terms judicial activism and liberal media bias. Both have cases where they have actually happened.
Of late, however, both terms have been used in very questionable circumstances. The Terri Schiavo case had people crying judicial activism when in fact the judges were solely interpreting the law as opposed to making up new law to suit the conservative position. Also, many are using liberal media bias to slam the messenger upon every unsatisfactory message. Maybe, just maybe, there really is some truth in the report. You may not trust that little wolf-crying brat, but it would still be smart to at least peek out the window.
