I agree with you in that the question of something being "political" is inherently related to the context, and that some things some people might find political (like the importance of voting from my original comment) are not "political enough" to be something which shouldn't be in a children's show.
I would also agree with you that pronouncing names generally is not (and largely probably should not be) a political topic, but that it necessarily is in this context because of it being included in a show about native Alaskans. If the teacher were inuit, or the student also white, or it was presented a simple misunderstanding along the lines of "can I call you T" "No please don't" "okay sorry I'll do my best" it would not be "political". Because it's in this show in this context and explicitly connected to previous abuses of native people being made to use "white names", my contention is that the creators of the show intend for it to be political .
