There is a degree of quasi-political messaging in PBS children's shows. I can say this because I've watched more hours than I'd like of several of them, but I'd like to focus on on Molly Of Denali. It's a good children's show about an inuit girl who lives in Alaska and teaches children general good morals and specifics of inuit and Alaskan culture.
When I say it's political, I mean that it makes points without nuance on historical and current issues which range from widely accepted and important ideas (example: They didn't let Native Alaskan People vote in the past, so it's important to exercise the right to vote now), to what I would consider less widely agreed upon and important ideas, such as it being deeply upsetting and disrespectful for a "white" teacher to call a native child "T", because she had trouble pronouncing his native name. Another example is them introducing the importance of "land acknowledgements" in a children's show. A final example is the "clueless white" trope wherein the offensive rude white visitor has to be educated by the wise natives over and over and over.
I'm not trying to say that any of these examples are "right" or "wrong", but they do represent "politics" in the mind of wide sections of the population.
This said I like the show and of course we need to fund public broadcasting, I would just prefer if we did our best to keep the most controversial stuff for when the kids are a bit older to make it a smaller target for outrage (from the right or left).
The most jarring part, to me personally, is the drastic shift in tone and presentation for injustices with wildly different levels of impact. Perhaps rudely, I think to myself in the voice of the Inuit grandfather from the show "The white man took me from my family, did not allow me to speak my language, beat me and did not allow me to vote, and worst of all...... He did not let me smile in photos"
I don't mean any of this as racist or disrespectful and I hope this is a nuanced comment for consideration and not a kneeejerk reaction or evidence of my subconscious biases run wild.
