You are missing the point. …it boils down to the fact that it is applied to women 99.2% of the time
Yeah, because the fact that the character is a precocious girl is part of what makes it such a transparently pandering trope.
while men get a free pass in the same situation.
I sure hope you mean “male characters,” since I don’t think any “men” have any superpowers, let alone overpowered omnipotence on Squirrelface’s level. And in any event, no they don’t. Movies with invincible male leads who are never in dramatic peril (such as most Steven Segal movies, where he never once gets hit) are as shitty and uninteresting as any Mary Sue vehicle.
