I find those with the "Question Authority" bumper stickers particularly annoying.
I agree with the sentiment, but sometimes the answer to the question is that the Authority is legitimate and should be obeyed. Those with the sticker never seem to recognize this reality.
The logical response to that bumper sticker is
"Sez Who?"
geography
n : study of the earth's surface; includes people's responses to topography and climate and soil and vegetation
They could at least call the class "How to be a raving lunatic with tenure and using the classroom as a way to indoctrinate the youth of America" so kids could know what they are getting in to.
The thing is that their idea of "authority" and my idea of it are different things. They don't question the "authority" of the MSM; I do. They don't question the "authority" of Liberals in power; I do.
Very good point that authority is often legitimate and should be obeyed, too.

I'll admit in my youth I had a bad bumper sticker that read: Save gas. Fart in a jar. *sigh*
