Frequently how it shows up on “No Stupid Questions” is that they’re pushing a bigoted agenda under the guise of “I’m just asking a question and everyone’s attacking me for it.” Like if someone came to No Stupid Questions and asked (and this is just an example, not my position at all) “why is there so much trans propaganda on Lemmy?” or whatever. (And in the thread when people are like “you’re a bigot” they respond with “I didn’t say anything bigoted. I just asked a question.”)

But yeah. Like what Xtallll said, it’s more generally using language/symbols that for the in group is a reference they’ll all get but for everyone else at least retains an air of plausible deniability. Often it’s done by politicians (particularly right-wing politicians) to try to straddle the fence between the extremits and more moderates in their party. If a politician speaks in support of “states’ rights,” they’ll get the vote of the extremists who know that “states’ rights” actually means racist policies and also the moderates who still think or perhaps are still deluding themselves that it means somthing vague but more benign.
