People keep saying that creativity is stifled today, but most of the people who say that are comedians who are upset they can't rely on tired cliches about women and minorities for cheap laughs. Which is the problem, isn't it? It's not that you have to walk on eggshells to avoid offending people, it's that the things that people found offensive came off as funny to you. (Editorial, not personal you). Ditzy blonde bimbos with big racks and small brains was funny, not demeaning. Homosexual men with heavy lisps were comedy gold! Who couldn't be amused by a Chinese doctor named Won Hung Lo. Can't you take a joke?!
We laughed because the humor was directed at us. White, male, straight, Christian, Middle class, American. The whole of media was made for us. And if you weren't us, well, don't take it to hard, it's just a joke. Or a little fan service to get the guys on board. I mean, how could you take a badass woman fighting off a hoard of inhuman aliens seriously if you didn't get to see her in her panties first?
And market was correcting for that. Did it overcorrect? Probably at times. Was the backlash that followed itself an overcorrection? Absolutely. When you are privileged, equality seems like oppression. But, as you said, the pendulum seems to swinging back at a higher velocity. Which means less people of color in prominent roles, more tokenism, more women reduced to eye candy roles, LGBT erasure, etc. at the rate we're going, slurs might even be back on the menu.
Or maybe we'll take those self-imposed "restrictions" to heart and find new ways to create art. I'm told D&D is best when not every option is on the table, and that curation is a key to creating interesting ideas. Consider this a curation. Do better. Create something new that's out of your comfort zone. And accept that it's all bigger than anyone's personal preferences.
