Rather than another social debate on coding, let's get to the real problem with functional programming: There are not enough good resources for it.

It doesn't matter as much if FP'ers are arrogant if you can just learn it properly without them.

I've read blogs, academic papers, chapters in books and more about FP, but I've really yet to find a clear, concise and mutually agreed upon starting point. The best example so far has been a hard to find essay from Recurse Center. Perhaps one exists, but the fact that my searching didn't yield one (and I have searched) might be a more substantive reason for why more people don't FP.
