The garbage starting prose/warnings are so annoying. I wish I could turn them off somehow. Even it's habit of restating the question at the start of its answer gets annoying when you just want the answer.
I probably took “world history” a half dozen times through grade school, high school, and college. In each case the history of the world ended in 1945 because everything that occurred afterward was considered “too controversial” for discussion in a public school. Fast forward a few decades and it’s happening again. A lot of stuff happened after 1945 that warrants discussion.
