Agreed. Clearly, some of us (myself included) have direct first-person experience with the phenomena that the OP claims does not exist. Maybe it is less common than in the past, but it clearly does exist to some extent. If some of us take care to scuff/clean/abrade a tire before fully stressing it, what's the harm? I don't think anyone is saying "I'm an awesome rider and these darn tires made me crash." We are just saying that it is something that people should be aware of in case it happens to them.
