You don't have to visit the extremes of politics to find the tinfoil hat brigade; Engadget has found that the ones who fear cell phones have moved on - they now fear WiFi:

some of them have found time to attack WiFi, and have had their first taste of success at a Canadian university, which has just banned wireless internet access. Officials at the school, Lakehead University, have banned WiFi, saying that they want to avoid "potential chronic exposure for our students." The officials point out that the "jury’s out" on the health risks from EMF generated by WiFi transmissions, and liken the risks of WiFi to those of second-hand tobacco smoke, which were not immediately apparent to researchers.

As Engadget says, someone should ask these clowns about cell phones, microwaves, TV's, and radios. There's no telling what those might be doing to their students either.
