Hot take: people spend way too much time talking about issues that don't matter, like LGBTQ and race (note: not to say that LGBTQ and race are unimportant issues. In fact, there needs to be equal rights and treatment in both categories. Just, comparatively, they are not as important), and way too little talking about things that really matter for the survival of humanity, like climate change and space travel.
Then what about the kids who like the subjective stuff? They teach everything because different kids may have different interests and may want to do something different in future (unrelated to highschool science)
How will they even have the interest if they aren’t exposed to it?
