It seems like it hasn't been mentioned here (I didn't find it anyway). But Netflix made audio description so blind people can get a better grip of Daredevil. http://blog.netflix.com/2015/04/netf...ption-for.html
We saw it with Rocket in Birds of Prey
Static in Supergirl
Eli Bradley in everything
The real Wally West
and poor Cassandra Cain who got edited out of books
So some writers might be telling the truth.
And this is where we need to start asking editors why. Who are they serving? You can't keep pandering to the group who doesn't like minorities or LGBT.
