In my experience, it’s mostly a vet/military thing. Rednecks fly the actual confederate battle flag. It could be cop, but they typically fly the thin blue line flag. Subdued/monochrome flags are pretty popular accesories in military and military adjacent communities. If you check out “Grunt Style” you’ll probably see dozens. And enlisted (grunts in particular) tend to skew less educated and are more entrenched in toxic ideals of masculinity, so it’s no surprise to see them acting like fools on the road.

Don’t forget “Lemmy feels higher quality than reddit” followed by several hot posts that are compressed and re-reposted memes with pixel densities low enough to count.

And the “I’m glad Lemmy doesn’t have the reddit hivemind” followed by posts with whole threads of comments straight out of reddit “AmericaBad” thought train.

Pretty much, all of these things can be summed up by “suddenly acting better than reddit while acting identically”, I guess.
