When Professor Port asked the class about Faunus discrimination, he specifically said, "Because of your Faunus heritage." Now I think this implies that there is indeed a genetic factor, and that being a Faunus is comparable to having blue eyes. A recessive gene, but a common one nonetheless.

There is also the possibility that the Faunus have some sort of connection to the Creatures of Grimm, and that might be the root of discrimination against them.
