It's indeed very stupid that Quasar could break the planetary shield considering how easily it withstood the combined powers of multiple herald-to-trans-level heroes. Then again, the entire premise was very stupid as well: SHIELD/Hydra shouldn't be able to create and maintain such a cosmicly powerful force field around the entire Earth in the first place. The fact that it was apparently thousands of times more powerful than the shields generated by the likes of Invisible Woman or Magneto also diminishes these superbeings. Apparently by some casual technological means it's now possible to generate energy shields far more powerful than those of the force-field-generating herald-level superbeings.
That said, I can't see how this is a feminism / female favoritism issue. Many female superheroes failed at breaking the shield as well, including Monica, Carol and Janethor.
