Because a lot of young male gamers are not mature enough to examine their own prejudices and take her points as an opportunity to grow. For many young gamer males - a game world is the one place where they are not impotent. Its the one environment they can exercise control over.
Its far easier for them to issue anonymous threats that they don't have to be accountable for than actually make an attempt to understand the value in what she is saying. Of course their reaction has totally validated every one of her criticisms but its far easier to attack the messanger as being somehow illegitmate than seriously examine the merits of her points.
For young male gamers who typically have no close female friends and no skills to bridge the gap - she sounds like an alien. The fundamental problem is one of self awareness.
I've seen similar insanity where devs have introduced gay characters in their games. A certain segment of gamers reject the notion of being prejudiced - by behaving in an entirely prejudiced way. They simply don't have an understanding of what prejudice means or how damaging it is to others.
