I think everyone is misunderstanding this statement. The line of thinking here is that we're all human, and race should be a "non-issue" - black/white/asian/hispanic/etc. should all be treated the same way. It's a statement that we should transcend racism, not ignore it. Delsin from inFamous: SS is a good example. He's Native American, and it's touched upon, but he's mostly just "Delsin" and not stereotyped or categorized into ethnic tropes.
I know most people see statements like this and think "wishful thinking" or "how nice it is to ignore the world's problems", but this is really the line of thinking we need to get to if racism if ever going to go away. Of course, we can't just zip to the finish line and ignore all the baby steps we have to take to get there, but the attack on z-layrex here is a misunderstanding, I think.

But what does that have to do with the lack of representation in the industry?
I guess that means games should have an equal amount of each race or no race at all?
