They just gloss over copying his gun to mass produce it now smh. Should only be making 1 time use bombs
They copied the concept of using a metal tube to contain an explosion to propel another piece of metal down the tube at a target, moving at lethal speeds. They did not directly copy his gun. In fact, they reverse-engineered it and then adapted it to their magic system. Lot safer for them, too, because there's no gunpowder to ignite with fire.
When you are searching a database or discussing the classifications of material, that's not really a concern. When you take it out of context, it might seem inappropriate, like a whole lot of things. Another example that comes to mind is "trap"/"reverse trap". They apparently are also hated by some.
Yup, same problem. It's declaring that it being one way is the default, the "normal", and everything else in the same vein is compared and contrasted to it.
But it's clearly a classification thing, even if it's used a whole lot in discussions. You can write crossdressing to cover them both, but, consequently, you don't then know which way it goes, which is a pretty big thing. Generally speaking classification terms are better shorter than longer. Though as database technology has developed, it has become less of a concern if the developer puts a little bit of effort into it, allowing suggestions, redirection of synonyms, and such.
As you yourself said, there are plenty of other ways to classify it, but shorter is generally better. "Female Trap" is even shorter than "Reverse Trap", for instance. "F2M Rape", "M2F Rape", "F2F Rape", "M2M Rape" or their full-word counterparts would all be much better catagorizations for fictional works, so people can find exactly what they're looking for, too, while also being far more accurate and not demeaning by implication.
That's a pretty important detail to adapt out.
And it still doesn't answer why they wouldn't just ask him.
I honestly can't remember the reasoning that was given at this time, sorry. But yeah, a lot of thinking type scenes end up cut when LNs/WNs/books in general get adapted to other media, but especially visual media.
