I really wish classes on basic philosophy and skepticism/propaganda techniques were taught in high school as mandatory class. People need to learn to question propaganda and demand sources and logic when people try to "convince" them of "thangs and stuff". Too many youngsters trust the crap on the internet without question if it makes them "feel" good or "a part of something" or any other number of emotional responses to tiktoks and instagram tripe.
You get philosophy at any Catholic or Jewish school simply from your theology class and "skepticism/propaganda" is usually called "rhetorical analysis" and is taught to high school Sophomores in English class.
I can't speak to Protestant / "Christian" schools because theirs is a very different religion but a Catholic education is 12 years of moral philosophy and formal ethics. It's just filtered through the writings of prominent Catholic theologians whose ideas are informed by but ultimately separate from the bible.
Despite being an atheist I think my theology classes were the most valuable ones I had growing up because more so than any other class, even math which would go on to study, they taught me how to think for myself. I'm sad a secular version of it isn't taught everywhere as standard curriculum.
