Professor Oobleck's lecture confirms that. Human persecution of Faunus reached the point that, at one time, there was a war between the two species when humanity tried to restrict the Faunus to a reservation-like prison-nation called (with spectacular lack of tact) Menagerie. The Faunus won that one and, I think, like the more racist elements of the Confederacy, the human supermacists have neither forgiven nor forgotten.

So, yeah, at least some of the human students at Beacon are likely from sub-cultures that routinely demonise all Faunus as subhumans who have ideas above their station.
