Yeah this seems generally opposed to the concept of a general education. I get that many people don't like that they had to learn all these things in an environment that generally sucked to be in, but also basic understanding of math, science, language, music, etc is just a nice thing for everyone to possess.

Like several of these things will be tangentially encountered at various points in your life. Yeah I've never had to write in cursive, but I've had to read it. I haven't done much chemistry since college, but carbon sure comes into the news a whole lot. I don't use a protractor much, but I've had to imagine them for various uses of space. I don't diagram sentences often, but it's really useful when learning a foreign language, and also way too much of the country thinks pronouns were invented in the 21st century. Communal making of music is something that used to be normal as a fun way to pass an evening and recorders are cheap and easy for children to learn.
