Working with Haskell requires no Category Theory.

It's a fun language, and if you play with it and its ecosystem, it might give you ideas to import in your own environment.

Pick up a good book, and learn it, because it's fun. And no, you're not too dumb to learn it. Java and its ecosystem can be more complicated IMO, you don't realize it because you've put years in learning it.

Agreed it requires no category theory, but I'm an experienced programmer in a few languages and I've found it very hard to learn. I can get to a basic level, where I write rather verbose programs because of all the recursion and immutability, and I sense that I need to make better to use of the core abstractions that the language is known for (those with names which point to concepts in abstract algebra and category theory), and I've totally failed to do that in the two times I've spent a few weeks trying to learn.

Advice gratefully received!
