Lets skip the rigmarole and get to the part where we recognize that people referring to anime in general, when saying they want things "from anime", isn't an egregious offense that needs to be litigated by rigidly defining what that means else the argument that people aren't universally attracted to things "from anime" be made invalidated.
Not all fantasy ever written in in a particular genre, medium, or whatever is assumed to be included when we refer to them so to try and make this argument that referring to anime in general implies all anime ever produced is just ridiculous.
We all know what people are talking about when we talk about whether or not things "from anime" should be a part of the game. This useless argument to try and weasel out from acknowledging that needs to be dropped yesterday.
