The myth is that the differences (in mental rotation ability) are innate or "biological", not that there is differences (in mental rotation ability) in the first place.
If one gender displays innate ability and the other can be trained to match it, then the difference is not shown to be a myth. There is a very dishonest redefinition of a common word involved to make the meaning apply.
Political fictions are comfortable but don't really change facts, they just color interpretations. Mischaracterizing observation does not serve to make an argument appear stronger.
Note that none of this means women are inferior, and if you are construing my point to mean I am arguing for that position, you have imposed that on me.
I was referring to mental rotation ability, I clarified it in an edit.
I also don't have time to go into the studies you linked about general differences but similar studies have been debunked before. For example with 1.5 day old infants where the experimenters knew about the sex and their bias subtly corrupted the experiment and it did not reproduce when the bias was truly accounted for.
