Ark Times and "Judicial Activism"

I noticed the lefties at the Arkansas Times were claiming that conservatives were hypocrites on judicial activism because we applaud a federal court's ruling that the federal mandate to purchase health insurance is unconstitutional. They may need to be educated on what judicial activism is. It's not simply a matter of the courts declaring some act of the legislature or action of the executive to be unconstitutional. Courts are supposed to do that. It's when they do it without regard for the actual words of the Constitution and the original intent of the people who wrote those words that it becomes judicial activism.
