How about it is just reality. Radio transmission receivers exist, we make them and use them all of them time. Now we are just starting to learn about nano structures and what can be done with them. Odd genetics, exposure to non-normal environmental toxins and pollutants and heavy metal build up, upon an evolutionary basis. Self righteous arsholes of course just don't care about people and will attack them for any reason at all. Out of 7 Billion people is it likely that some people will be much more affected by radio transmissions than others absofuckinglutely. Some people can eat peanuts and for others it is a widely dangerous poison and it will kill them. Could some people develop weird nanostructures that make them vulnerable to radio transmission, say something along the lines of RFID chips, sure, weird shit happens. Start doing statistical stuff with numbers in the range of 7 billion and near anything becomes probable.
