Ian Sattler's Been Reading Too Many 70's Comics
Thanks to Saranga, I read the following quote from DC Senior Story Editor Ian Sattler (emphasis mine):
"It's so hard for me to be on the other side because it's not our intention. There is a reason behind it all. We don't see it that way and strive very hard to have a diverse DCU. I mean, we have green, pink, and blue characters. We have the Great Ten out there and I have counter statistics, but I won't get into that. It's not how we perceived it. We get the same thing about how we treat our female characters."
Now where have I heard that before? Oh, yeah.....
This is from Superboy and the Legion of Super-Heroes#216, "The Hero Who Hated the Legion", by Cary Bates and Mike Grell, from back in April 1976.
Ironically, the Legion's racial makeup has been recently regressed to around where it was at the point this story took place.
