I'm allergic to oxygen. I'm being discriminated against because my lungs hurt every time I breathe. Ban oxygen. It's just unfair.

Maybe if the guy had said 'I don't want to my body saturated with microwave radiation.' people would take him seriously, then again, most upon hearing microwave would think burrito, begin to salivate, and head to 7/11, NOM NOM NOM

Take him seriously long enough to suggest he get the fuck off planet Earth, which is bombarded with radiation 24/7.

Fun related exercise: next time you're in your car driving, listening to the radio, consider that your radio is passive, not active. You and your radio both are powering through a massive soup of signals, some of which you choose to convert into audio depending on your tastes, but all of which permeate your body on a constant basis.

Further food for thought: Picture the full electromagnetic spectrum as a measuring tape stretched out 2500 miles. The visible portion would be somewhere around the middle 2 inches of tape.

Radio waves (where WiFi lives) have the lowest amplitude and frequency and are among the least destructive to organic tissue.

This guys a jag, plain & simple.
