I don’t care if the teacher taught knitting
There was a time in this country when we were in a world war. Many German-Americans, in fear of being interred or losing their jobs and homes, hid their family Bibles and rushed to change their names as an outward sign of loyalty to the USA. For years after the war, having a German surname was a handicap.
promoting bigotry -to children- towards someone of German ancestry simply for changing their name to an anglicized version, is exactly the same as promoting bigotry towards someone of Cuban ancestry for changing their name to “Ted” or someone of India ancestry for changing their name to “Jim”.
The school made the right call.
I understand all of that. What I don’t know is the purpose of showing the video to the students. Without that, I cannot make a fully informed conclusion.
Your conclusion is based on the assumption that the teacher had a nefarious purpose. You may be correct, but you don’t know that based on the information contained in the article.
If he taught “cultural studies” and showed the video to point out the lesson that you just outlined, you might be fine with it. If he taught “media communications” and the purpose was to demonstrate how a satirical news show influenced a social media trend (#MakeDonaldDrumpfAgain), I might be fine with it.
The point is, we don’t have all the facts.
