I just picked it out as a very concrete example of a statement that could provoke a substantial negative reaction.

If it hasn't happened yet, that's at least some evidence it won't happen. Do you have reason to imagine a scenario which makes things very much worse than they already are based on such an effect, which means we must take care to tiptoe around these possibilities without allowing even one to happen? Because if not, we should probably worry about the things that already go wrong more than the things that might go wrong but haven't yet.
