Besides those toxic people who claim something and everyone else is wrong, its not too bad. In the end, all it is about is just one tells someone else a specific definition of a word. And in a sense he is always right, because he (or she) is defining it at that moment.

I understand what you are saying there (last paragraph), but, there is context if one says Wine is not an emulator (not because of its name). The reason is, we are talking about software emulation in the sense of gaming. And there are emulators to play videogames literally emulating other systems. And we have other words to make a category for distinguishing reasons such as Virtual Machines or API compatible or ABI compatible too. I'm fully aware of the fuzzyness of the terms. I'm also fully aware what upsets you when people tell others Wine is not an emulator. But they do it with intentions to teach (such as you and me here), at least usually. Trolls aside or "idiots" aside.

So looks like you are right; we agree each other us here.
