I'm curious about the logical leap you made when you stated;

  Accept the side effect that quality is lower.

I'm also curious about the following;

  Currently, I can observe females in computer science simply being there for the quota, while more competent males get rejected. 

Without actually statistically backing it up and there being a significant different in performance. It's pretty anecdotal.

Tell me, for someone who makes these types of logical leaps and uses anecdotal quips to support a bigoted statement -- do you believe yourself to be a "quality" employee? Because I'd fire you.
