Well, that really depends.

Though the strongest reason I could think of why the Faunus are not related to the Grimm, is because that they were never compared to the Grimm.

Even if we assume that Cardin Winchester is ignorant, and hence he made his racial remarks based on a faunu's animal features alone, it is clear from Episode 1 however that the Faunus are being discriminated like an animal - they were holding such a sign themselves! if they were being compared to the Grimm, then it should be something like 'We Are Not Monsters!' We've already mentioned above that there is at least some form of distinction between the two terms 'animal' and 'Grimm'.

If we follow by your theory, then the Faunus should've been hated for being 'born evil' or 'Grim-like' or just outright 'monsters', instead of using the tamer term of 'animal'. If there's one thing we know about humans, it's that when it comes to criticism and insults, they will always go for the worst possible choices.
