You're not giving me anything to work with by saying "Someone, somewhere said '5G bad,'" but I obviously don't believe them. Electromagnetic radiation can be harmful through its quality or its quantity, and neither applies here. The damage caused by ionising radiation requires more energetic forms of light than visible light, like ultraviolet light or X-rays, while microwaves are orders of magnitude less energetic than the already-safe visible light. Neither pulsed nor unpulsed microwaves are dangerous except through the Archimedes heat ray method of sheer brute volume, and it's simply not credible that people wouldn't notice that a communications antenna was drawing as much power as a military radar transmitter or putting out so much radiation that it was literally cooking people.
