All EM waves can interact with molecules in our bodies, that’s true.

But all of the interaction is thermal, not ionizing. And the energy levels are so tiny that the thermal impact is much less than the thermal impact of opening or closing a window on a warm day.

Microwave ovens have thermal interactions with the food inside them, because the microwave runs at tens of thousands of times higher power than is used for radio frequency signaling.

2.4 GHz WiFi isn’t microwaving our bodies, and neither will 5G.

Restricting the harm window to ionising radiation is a red herring.

We know that magnetic fields alone have very apparent interactions with humans and other living organisms[1].

The only mitigating factor here is the TRP, but at the FCC limit of 500 watts ERP per channel, that's actually not too far off from microwave ovens. I doubt it'll hurt humans unless they happen to live in the immediate path of an eNodeB, but I don't think either one of us is qualified to speculate about what it'll do to inspects and birds that will pass much closer to it.

Your wifi router isn't cooking you because it's at a significantly lower ERP than a microwave oven, but the same is not true for a mobile cell.

I will not dispute that if you are less than a meter from a transmitting cell tower, you might be uncomfortable.

But the induced magnetic fields from this level of power, dispersed at an inverse square rate, which isn’t penetrating far past the skin, just doesn’t seem reasonable to fear.
