I mean we could ban 80% of all Indian food because first time westerners eat it they react much stronger to the spicy ness than they would to smoking.
Stating independent of the actual science that “It was always obvious that smoking caused cancer” isn’t any better than the people stating now that “obviously EM radiation causes cancer”.
Same with asbestos, lead in gas/paint, uranium lipsticks, &c.
Whereas with smoking we can see over ten times higher risks for certain types of cancer-related deaths. That doesn't mean there's no effect due to mobile phones, but I think if it were remotely comparable to smoking we'd see a significant impact by now.
This is similar to homeopathy. Even if the state of research is not great, we're discussing a theory that is just not physically plausible. The default assumption should be that it is wrong.
