The statement you took issue with was I think Mill either ignored or did not anticipate just how dangerous a viral bad idea can be on a global scale.
Nobody argued that Mill held ideas to be dangerous; if anything, that is being suggested as a shortcoming of Mill's philosophy. There is no good reason to solicit evidence for a proposition which nobody was making to begin with.
