I don't disagree that somebody who knows OOP but not FP needs a lot more information than I gave. Where we disagree is on the notion that I need to explain everything in detail when there are fountains of material out there. If anything, the purpose of my comments is to make you think, "Is it hyperbole, or is he on to something? Maybe I should look into this further."

I was an imperative programmer for a decade before I looked at functional languages, and it was because of glowing but unfamiliar praise that I looked deeply in the first place. Now I know that a lot of that praise was warranted. Everyone's different!

Also, as I noted in another comment, the "elementary school" comment was not meant to imply that it's simple--alas, one of my main gripes with OOP is that it isn't simple in the ways it needs to be--just that it's something you're almost certainly exposed to early on, so it quickly becomes what's familiar.

Just wanted to note that the "elementary school" comment in the original post rang true with me. When I was learning OOP, my first program was literally about animals (cows, chicken, sheep) making sounds. A cow says "Moo", a sheep says "Baa", a chicken says "Cluck-cluck", an Animal says "Error: this method shouldn't be executing" or something.
