Dear me! How extraordinarily easy plain language seems to get misunderstood/misread on the internet.
What I meant - and what I thought I'd made clear - ie what was written - was that imho reports of "severe" icing or turbulence are usually exaggerations. I didn't use the word "overstated" with or without the word "hazard", and clearly my post made no implication whatsoever that I thought the effects of severe icing are overstated or exaggerated, as I has used the example in conjunction with the word "reports".
Clearer now?
