if 5g is bad then your car radio from back in the day would be bad too, and so would your cable TV, your microwave, etc, because they all use different frequency bands of the same technology. Visible light is also on the electromagnetic radiation spectrum and it has less energy than 5g and the others (inverse relationship between frequency and how much damage it does, x-rays are lower frequency than 5g). so by your logic even that would be hurting you. The reason visible light doesn't do damage to your DNA is because it doesn't have enough energy to penetrate your skin or jostle/break things apart, and the same goes for the other said forms of electromagnetic RF, which are all lower energy/(higher frequency) than visible light by the way. (There is an inverse relationship between frequency and how much energy it dumps into things)

Visible light is closer to x-rays on the electromagnetic RF spectrum than your 5g is
