When I was trying to learn monads no one ever gave me an example of mapping a list-returning function to a list. Everyone went on about 'effects', monad laws, etc. For some of us it's best to work backwards from something concrete and then show why the laws are important.

I love how simple most things are in FP compared to OO. I also hate how poorly FP concepts are explained.

I'm not saying you're wrong about people learning terminology. However, you definitely get more strange looks from FP terms than OO terms. Class, interface and object are common terms. When I mention a word like 'monad', 'monoid', 'magma', or 'functor' people look at me like I'm nuts. It's not logical. A new word is a new word. It's just FP words sound almost alien and trigger extra confusion in people.
