I guess I'm late to the party - what does population have to do with any potential/speculated dangers of 5G?
Hans Rosling is a gem. Highly recommended.
A quick skim over the posts shows the thread has gone as sort of expected - those who go in believing that there may be a danger, and others coming from a standpoint that all non-ionizing radiation is completely safe and does zero harm. Also the C-word thrown about for emotive effect (by both sides). I like to think I'm 'neutral' but of course, there is no such thing, we all have our biases and assumptions.
Just because a large number of "Scientists" talk openly about fears of EM (specifically radio and microwave) radiation and potential "negative health effects" doesn't really mean much without knowing who these Scientists are, their field, their qualifications, and their background. But similarly, just because we all live in a sea of man-made radio and microwaves, without all "dropping over" doesn't mean that there aren't any mild long term effects (be they negative, neutral or even positive). It just shows that any long term effects that exist must be subtle, or perhaps masked by other things like diet/lifestyle.
Also, once one starts to think in terms of secondary and tertiary effects, it becomes even more difficult to prove any causal links, but also much easier to speculate about them. For example, I could kick out some wild speculation about how areas of greater EM "pollution" cause an increase in headaches, which increases the consumption of paracetamol, which causes a small uptick in liver disease, that could only be found if one looks for it. - there are a hell of a lot of assumptions there, especially just saying 'EM causes headaches' without any kind of proof, but it is also rather difficult to completely disprove.
And that is why there will always be fears around any kind of "radiation" regardless of peoples education, "class" and even by those who study in that field. Those on the other side who immediately call "woo" on it (as tempted as I am to do), are only serving to re-enforce the fears by patronizing and immediately dismissing peoples fears - that's why we live in this so-called 'post-truth' era. It's all well and good being smug, and claiming you are 'more educated' but in fact its that attitude that is harming science and education.
