> So you're proposing to push people to speak at conferences who aren't necessarily the most knowledgeable speakers, simply because they have the correct gender or skin color?

On the contrary :

   Conferences are simply showing up the diversity problem    
   in a particularly acute way – we will never fix it by 
   pretending the industry is more evenly distributed than 
   it actually is, and later blaming organisers for it.
