You mean like infra-red from the Sun when we have homes with windows?
(A microwave is ~1 KiloWatt up close, WiFi is ~1Watt and meters away. This is like spreading fear that your house has a warm radiator which is bad because ovens use warmth to cook food).
Not only is there a massive difference in the power of a microwave oven compared to wifi, but the mechanism through which it heats food is dielectric heating [0] which does not occur in radio signals because they are not rotating fields.
This basic information is contained in the first very short paragraph of how a microwave oven works on wikipedia.
I hear these concerns in real life and as per my longer post above, I don't understand the threat model. My oven and stove can also cook meat. It's what they do. What is the actual concern? I feel I have burned myself on ovens and stoves a lot more than I have on microwaves in my life (let alone the risks in popular gas stoves etc). I am genuinely curious what is the delta and differentiating factor making microwaved mystically scary?
The only adverse effect microwaves have been found to have on humans is due to heating [1]. WiFi transmitters emit less than 1/1000 the power that a microwave oven does. Unless your cell phone starts to make you feel uncomfortably warm, I don't think you have to worry.
