Category theory is also so abstract that you can literally find it in everything. So it's not like it doesn't apply, it applies to everything.
When I say Haskell is a category theory framework I mean that Haskell has primitives that are explicitly modeled after CT and named with the same mathematical names. You don't have to know CT from a mathematical angle to use Haskell but it doesn't change the fact you are using CT primitives like functor to build things.
Other languages have CT concepts like functors but they don't crystallize the concept in such a pure and explicit form. That's just my opinion on it. You are welcome to disagree.
But when you say garbage like "100% nonsense" it's just fucking rude and against the rules here at HN. Don't say it again. Speak respectfully or don't speak at all.
I found that commment to be seriously rude and disrespectful. Yes I should have avoided the "100% nonsense" comment. However that doesn't give you licence to be rude and abusive in return.
I mean you expect me to just stand here and get raped by your rudeness? No reasonable man with spine will take that shit in real life and that's also typically why you don't likely speak that way in real life.
