Only the Alt-Left MSM pushes the false narrative that the Right uses a concocted term like "boogaloo". This is right up there with the Left pushing the absurd idea that the "OK" sign is somehow a nazi signal. Or a green cartoon frog names "Pepe" is racist. Both of those were originally generated on 4chan/8chan as pranks, but the Left was actually stupid enough to buy in.

Same thing happened with the original, reconstruction era KKK.
