I think I actually made a theory of that.

I mean, no matter how you look at it, judging from all we've seen, most of the animals in Remnant (or at least Vale) seem to be the Grimm. If we hear about a furry beast, we think a bear or something. But if they hear about a furry beast, they think of Grimm.

And the Faunus are half-animals. As such, it's possible humans long ago thought that the Faunus were at least half-Grimm, instead of simply half-animal.

As for that being possible, look at it this way: Faunus: half-human, half-Grimm, with the Grimm side being the animal parts which look relatively normal because the human part has a Soul, which "purifies" the Grimm part and allows the Faunus to have a Soul despite being half-Grimm.
