We can't know that the DeeDee situation wasn't about race though. That hasn't been decided in the story yet, and whether we believe it or not in the end, we don't have the information yet to decide. It's never been suggested that there was racism - just that the protocols for spotting distress involve things like going pale, which clearly won't apply to someone with black skin. Raising awareness of that can only be for the best, I think.
There are many instances where things are designed for men and leave women in danger - seat belts are a case in point, and I believe that crash test dummies are based on the male body, so airbags are designed to benefit men, too. Heart attacks present differently in women, and there will be numerous other examples, I'm sure. The more education about all of this the better, whether they are on sex or racial lines.
