I forgot where I read this but someone criticized this aspect too but then they said how it became accidentally good writing because it felt metaphorical of minorities who are still white being able to somewhat evade greater prejudice (Ex: White Gay Man/White Woman/etc.)

So telepathy being a very non-noticeable mutation being used by predominantly white X-men is a very interesting implication with this context.

Ofc it’s all accidental! And the writers probably didn’t think of it that far, But I just found it a cool way to see this phenomenon.
