Works of fiction are not real life. One of the purposes (maybe THE purpose) of fiction is to explore the unconscious, including (especially) the darker areas. We are, fundamentally, a predator species (sharp teeth, meat eating, persistence hunters), and despite tens of thousands of years of stuff accumulating on top of that, the base urges and instincts remain the same. It is better to exorcise those "demons" in contained places where they can do no harm than to let them fester in the dark. That which is feared and revered becomes powerful, that which is trivialized becomes largely harmless.
And even all that said, this is a very modest dipping into these themes. If they're not for you, that's fine of course, but understand that they ARE for a lot of people. The whole of BDSM essentially grows out of this, and it's not one-sided either. People enjoy throwing others around, but a whole lot of people enjoy GETTING thrown around too (and it fact that's the main audience for this game).
On your last point: In my experience the fandom is simultaneously one of the best and worst groups of people out there. Most are incredibly kind, patient, generous, creative and so on. But it's also a community of people built on the idea of being outcasts (like nerds, geeks, "gamers" etc), which makes its members extremely hesitant to gatekeep or have hard limits or boundaries, and this in turn leads to exploitation by bad actors who would have been much more rapidly shown the door in other circles. To be clear, I am NOT advocating the witch hunt nonsense that has devoured the internet in recent years. Encouraging dogpiles over minor things or fabricated evidence is bullshit. But if there is clear, severe evidence that someone is up to seriously terrible shit, and has been for a while, people should obviously warn others to stay away. What I make is adult entertainment, for adults. It's clearly marked as such. This isn't a physical store, I can't card people (and trying to do so online is impractical and dangerous for a variety of reasons), but this is an adult product with an adult intended audience.
