I think that what annoys some (and I'm guilty of it sometimes myself) is that some people use faulty logic. They want so much to BELIEVE in paranormal things, like some "alien" origin for the circles, or some strange Government conspiracy, that they blow right by Occam's Razor.
The actual simplest explanation is, and always has been, that they are made by humans with ingenuity and cleverness. For some, however, that is simply TOO simple, and not nearly as romantic.
Not me. I don't want to believe anything I want to know. FWIW several years ago I saw a program that showed clear video of unbroken stalks of wheat, normal resolution and magnified in a large CS. I grew up in eastern CO and I know what wheat stalks are like and you can't do that by bending it over, however gently, at any stage of growth. They also showed the elongation of cells in the bent area of every stalk. They didn't seem like flaky scientists at all. There were no footprints in or out of the field at all.
I don't believe in space aliens or energetic electronic atmospheric power bursts that create geometric designs but I have yet to see convincing explanations of how some low-tech jokers did that over night. You have some answers. That's very cool!
