First, why must we help the oppressed when their local oppressors aren't concerned? Is this what you're asking? You can't possibly be serious.
Second, just because a majority of Afghani men believe something doesn't mean they all do. Those girls presumably had some support in pursuing robotics. It's more than likely the men in their family are supportive.
If there's one thing I would expect everyone to agree on, it's that helping those girls is a noble goal. They are competing on an international level despite living in an environment that stifles their creativity and freedom.
