Well then you're definitely ahead of me in that respect. And for that, I congratulate you. That's a difficult position to achieve. I also imagine that your experience in the industry is unique. You may very well have had no issue developing male and female characters in the same way. That doesn't mean it applies to the entire industry.
Also, just calling my thought experiment ludicrous doesn't make it less valid. Why is it ludicrous? What about it is wrong with respect to the larger point I made? I honestly think it's worth discussing and just calling it ludicrous is avoiding that discussion.
Writing human beings sounds like a perfect solution for a perfect world. We don't live in a perfect world, though. People react differently to certain characters. If a man had worn Mockingbird's famous "feminist agenda" shirt, would the reaction have been the same? It might have been for you and me, but what about the millions of other people on this world that aren't wired the same?
