The only difference I see is that “dark” is understood as unknown and not necessarily a single thing.
A lot of older stuff we talk about seems to be assertive in their existence and what they are. Not all of course, but in the absence of a term that indicates “we really don’t know”, it seems random ideas were pretty common.
That’s not to say we don’t still do that, but I think it’ll be ideas that came out of or overly supported “dark” nomenclature. Like, say we find out we got Hubble’s constant wrong. I don’t think history will remember us as “believing in dark energy”. Just that we got Hubble’s constant wrong.
Can’t tell if this is empathy or we are already resorting to deporting people who haven’t even made it to the US yet. /s
