I'm actually going to amend my response to that ask earlier, because talking with the couple other black people in this space reminded me of some things.
Namely that *literally every staple trope* within mechsploitation - the medical experimentation, the enslavement, the mental conditioning, the sexual abuse, even the goddamn muzzles - every single one of them is something that actually happened to us in our real life history here in the US. You name it, we lived it. And WOW, that is something to reconcile with a desire to participate in the space and make stuff. Knowing that the toys the people here play with are far more dangerous to you than them, that they are Real and carry weight and meaning beyond the level of aesthetic. There is potential there, yes, but there is also great and terrible risk. It practically mandates that the genre be approached differently.
So, my amendment is this; while it's easier on a textual level to make mechsploitation stuff compared to older Empty Spaces archetypes, it's MUCH harder to engage with it as a black person, because it lacks the flexibility of interpretation that the ES archetypes did. For ES, the issue is barrier to entry, for mechsplo, the issue is the imagery, symbolism, and tropes used themselves, and that's a much higher bar to clear. So each has its own pros and cons.
It also completely explains why I have yet to see a single black Hound in any of these stories, because I can sense most writers, who are largely white (as was the case in ES too) understand this on some level.
