I never get the hand waving types. I think knowing the danger of something is the only bit of knowledge they have on a subject. So prove they understand it they go about lecturing people on how dangerous it is instead of actually understanding the subject. Otherwise they would understand that while dangerous in an uncontrolled environment we understand how to mitigate danger and design/build/use something responsibly. This is why we cant have nice things. Know-it-all danger rangers just ruin it with paranoia and ignorance.
