The Reddits for the different functional programming languages are a good place to hangout (and a frequent source of blogs and videos on these topics), and for FP in non-FP languages, there are good Github communities (e.g. http://github.com/fantasyland/, no association with FIOL).
I'd also humbly suggest that LambdaConf 2017 (May 25-27) is a great place to learn more about functional programming. There will be a special two-day LambdaConf workshop prior to the conference that introduces the basics of functional programming (no background knowledge), another that is aimed at a slightly more experience audience, and then at the subsequent conference, plenty of workshops and sessions to learn many of these topics (and others).
It's a journey, but everyone can get there if they have the interest. Most of the resources out there (blogs, videos, even e-books) are free, and the remainder are low-cost if you are already working in tech.
Good luck and please just let any of us lurker functional programmers know if you need a hand. :)
