This is bullshit. Anyone who knows anything about linguistics can tell you that languages aren’t objectively easier or more difficult to learn. What makes a language easy is its similarity to a learner’s native language, or other languages they’ve already learned. Furthermore, there’s a myth that certain things or ideas can be said or expressed in some languages but not in others, and this too is objectively untrue. All languages do the same thing, they just do it differently. If one language doesn’t have a word for something, that doesn’t mean it can’t express the concept, just that it has to do so through other means, typically in a sentence or phrase.
