If so, what is it?
Here are some quotes which are purported to be from the 'was that a gadfly comment?' department:
'Oh, to be able to be a gadfly!' --Terry Gilliam(BBC Article). Either way, it changes when you add 'polemic' to the fray. That word comes from a Greek word attached to the concept "war", and is explained in part by:
'Sacred cows make the tastiest hamburgers.' -- Abbie Hoffman
'Life in Lubbock, Texas, taught me two things: One is that God loves you and you're going to burn in hell. The other is that sex is the most awful, filthy thing on earth and you should save it for someone you love.' -- Butch Hancock
'When a true genius appears in the world, you may know him by this sign, that the dunces are all in confederacy against him.' -- Jonathan Swift
polemic: 1638, "controversial argument or discussion," from Gk. polemikos "warlike, belligerent," from polemos "war." Meaning "one who writes in opposition to another" is attested from 1680.(Dictionary). How does the gadfly polemic syndrome morph into essentially a "repugnant ideology"? They become unfair.
"The worst offense that can be committed by a polemic is to stigmatize those who hold a contrary opinion as bad and immoral men." [John Stuart Mill, 1806-73]
Take the case of the new US president, Barak Obama, who has not yet taken office. Some in the world of "gadfly polemics" are making racial slurs against him, or otherwise condemning him, even before he has any legal power. While he still, pursuant to American law, has to wait.
Blogs can have a lot of good content but still tend to elevate their opinions and preferences over his national mandate (after all, he is president to "us" and to "them"). And whether or not he or anyone else could comply with the demands of the politics of these gadfly polemics on steroids, our Office Of The President is by design an office that will listen. Listen both to "us" and to "them".
Surely most people would agree that gadfly polemics steps over the line of enlightened dissent, and gets far afield and even into foolishness, when a fair and common decency ... "give him and/or her a fair chance" ... is yet to manifest.
