I don't get Ska hatred. It's fast, punky dance music for alternative clubs, you have to go out of your way to be exposed to it. It's not like its being continually replayed on "Billboard's top 20 hits" radio stations.
Also, it's older than Rock and Roll. It's from a time when big sound meant more band members, but the current music ecomony doesn't seem well suited to supporting acts with lots of members. I long for asignificant fourth wave ska revival.
Tbh the list of kids shows without ska would be shorter. It's constantly used in scene transitions or just moments meant to be exciting, but some shows just straight up have Ska intro songs, like Phineas and Ferb. Hell, Scooby Doo had an entire episode about an undead ska band called Rude Boy and the Ska-tastics.
The ska band The Aquabats had a kid's show in 2012-2014. Not sure about what age their audience is/was. I was actually into them when I was in high school before they got a show. Their music is really goofy and fun.
