I am writing an argument--no, a diatribe--against "never mind how event X happens, let's just say that it does happen. What then?" (And, yes, I know that I have used that formulation myself a couple of times.) My basic point is that how an event happens almost invariably affects the consequences of its happening--I will give examples from both pre- and post-1900. I'm getting so annoyed with that formulation that I really want to write a general attack on it, but don't know where to put it. It's not a specific what-if, it's not about current politics (Chat), it's not an original story, etc.
