Title is linkbait. The linked question isn't about the merits of functional programming. It's about a user trying to wrap their head around it.

Yes change the title. It's offensive because it isn't an accurate depiction of the content.
I don't understand what I am supposed to take away from this link. I basically agree with the top-rated answer; that approach looks to be about how I'd do it. Is there something unusual here?
EDIT: This comment was written at a time when the submission had a less descriptive title.
