(1) Many of those people making it weren't too experienced in reasonable alternatives.

(2) Many developers I know (also anecdotally) spent years studying OOP to get to the point where they can use most of its higher level patterns effectively, and judge FP based off a single class or toy project built in a some lisp derivative, or what they heard from a friend.

(3) Those people making the opposite claim actually had fair bit of experience with both methodologies, since it is hard to avoid OOP.

In other words, it seems like the claim "OOP fits the brain better" is a prevailing meme, largely among those who have not tested the claim effectively, while "FP is pretty good and we need to lean on it more" is fairly popular with those who have actually tested the claim, instead of relying on hearsay.

Obviously, my personal experience shouldn't convince you that your statement is wrong. (I was a big fan of OOP who devoted quite a bit of time learning software engineering with both classes and prototypes before trying out FP and finding out just how much OOP was silly and could be replaced with simpler, more composable FP ideas). Nor do I think that all of the claims made by the FP people are right. But realize that your statement DOES require significant evidence to back its claims, and that resorting to populism gives it relatively little real support.
