Ok, metaphor is obviously the wrong word here. But OP is making a specific claim, that people now would engage in certain behavior if they were around during the satanic panic.
Now there are two parts here that inspire curiosity: the exact nature of the behavior (or what it means to say DNI if, etc.), and why you would say that behavior would be engaged in (what causes are present that lead to people in general having this behavior trait). What people are asking about when they ask about metaphor is, what is it about people now, their current behaviors, thought processes, and reactions, that is leading you to conclude they would react in X way in Y situation. It isn't unreasonable to ask this, even if they lack the understanding to be clear about their curiosity.
The thought process is, "Here's a claim about behavior, the implication is that the behavior is bad (a judgement of badness always inflames interest), the OP might be drawing this conclusion if people are behaving similarly about something that is not the satanic panic (since people probably assume there isn't a current satanic panic), but something(s) else is occurring that's somehow similar, what is that something else?"
Because the post is phrased as a conditional (if this was true, this would also be true), the prima facie (on first look) reading is that it is not true (even if that isn't contained in the strict logical meaning of the words). That is to say, while there may be ongoing satanic panic with people including that DNI, phrasing it like this suggests to readers that this is not what's happening, but someone analogous is. This is because there is a general rule in conversation that if information is present, it is relevant, so to state a conditional implies it at least might not be currently true.
While there certainly some unreasonable reactions above, the core question represented by the metaphor question expressed by some comments is not an unreasonable reaction, and comes from an appropriate and good faith understanding of the OPs main claims.
Reading comprehension is not the issue here, miscommunication is.
