The solutions I am seeing are things like automatically accept peoples reactions to things because of what group they belong to. But I think there are also just solutions to this kind of discussion playing out on social media. And that is the constriction of creativity I am talking about (for instance you can see it in debates about cultural appropriation and fantasy settings-----which I think is getting much harder to navigate).
When someone tells me that I stepped on their toes, I tend to accept their word for it and attempt to be more mindful of my step going forth. Are the bounds my feet can traverse being "constricted" now? Sure, technically, but there is still plenty of space for me to walk freely, comfortably, and ably. The only thing that has really changed is that people are actually a little less tolerable about having their toes brazenly stepped upon and have a greater platform to voice their issues regarding my indifference, neglect, or even malice to their discomfort.
But let us consider this as well. Are the published works that we are seeing now in the RPG more or less diverse in their creative fantasy than they were before? I would actually wager that we are seeing a far greater diversity of tropes, imaginations, and settings than what we saw before. Even looking across the different settings of D&D, most fall within a "mostly the same" set of overlapping tropes. Some undoubtedly break the mold, but most reinforce it. So is this what unbridled creativity looks like? Greyhawk, Mystara, Forgotten Realms, Dragonlance, and Generic Fantasylandia no. 5?
Many of these newer works do not tread as heavily or often on toes as prior works. So I think that your worries about the "constriction of creativity" are misapplied, as it only applies to a small, problematic subset of fantasy rather than on the whole. But sure, if your preferred mode of fantasy RPG lies within that limited scope, then I could see how you would feel that your entire world is coming under assault. But for many who are effortlessly creating new fantasy works outside of that smaller subset, then it comes across as an unfounded complaint that is insensitive to the problems other people have experienced therein.
And it may genuinely be difficult for you to navigate this changing world. IME, it is important that we that try to the best of our abilities, showing good will and patience to others, being mindful of where we step. However, the answer to stepping repeatedly on people's toes is not to deny that we are doing it or that it is the fault of others. We should show a willingness to accept error, apologize, and learn from our mistakes. We will naturally step on toes from time to time. And sometimes if we look around, we may realize that we were walking unnecessarily close on top of people where we actually had a ballroom available at our leisure to dance.
I think (white) Americans are very lucky not to have been oppressed by anyone since George III - and that was about the mildest oppression possible. And they tend to project their experience onto other Europeans.
As a white native born and bred in the American South, with native family extending back to the time before the American Revolution, I am not particularly concerned with any imagined oppression my ancestors experienced, but, rather, with the long, dark legacy and consequences of the real racism, colonialism, and oppression that they enabled, performed, and defended. I will carry this albatross with me to my grave.
