I was just a bit too old to have ever been into Barney. It came out in 1992; I was born in 1986 -- six years old is right at the edge of its target audience. For some reason, though, the opening riff to "The Number Limbo" has stuck with me as I round forty years old, periodically popping into my head at random intervals like a parasitic ear worm. I actually didn't even know it was a "Barney" song until I googled it last night. It is a mystery how it burrowed into my subconscious, but it has found its place and it will not be dislodged.
I was born too late to be into Barney itself, but I was also old enough to remember the absolutely mass social hatred people had for Barney. I'm not talking about six- and seven-year-olds performatively rejecting Barney to prove they're not babies. That's at least developmentally appropriate -- though the dirty secret they don't tell you is that this sort of performative rejection is actually a sure-shot indicator you're still a kid. One of my firmest beliefs about human development is that teenagers reject all their "kids" interests to prove they're adults because they're nervous they're not -- then they go off to college and realize the one thing they can be sure they have in common with their new roommate is that they both loved Teenage Mutant Ninja Turtles as a kid. Actual adulthood is reached when one doesn't feel the need to prove it.
Anyway, I digress. The Barney-hate we all saw was not the kid-appropriate version; it was society-wide and very much an adult phenomenon. And this practice -- I dunno. I don't like it. A society-wide propensity towards hating things whose primary sin is that they make a lot of people -- here, small children -- happy is not a phenomenon we should be proud of.
Perhaps with Barney young parents have an excuse for the haterade. Nathaniel isn't quite at the age where he's consuming children's media, but I can imagine in a few years after hearing the theme song to Bluey or whatever for the 9554th time I will laugh bitterly at my "who is it hurting" naivete. But this phenomenon is larger than Barney or children's media. The exhausted young parents story doesn't explain why we all decided to hate Anne Hathaway for awhile. Or Guy Fieri. Or Richard Simmons (okay, homophobia can explain that last one pretty easily).
The reality is, we do seem to pick out random pop culture figures who've done nothing wrong but be too earnest in making people happy and decide we're going to enjoy ourselves by collectively hating them. It is a society-wide digression towards adolescence and bullying behavior, styled (just as with actual adolescence) as a form of sophistication. We should be much more ashamed than we are of indulging in it.
