We know that the Empire was prejudiced against non-humans. In Legends, it was a lot more explicit, but even in Canon, we don't see any non-human Imperial officers and the Empire was fine with enslaving and committing genocide against non-humans, as seen with the Wookiees and Lasats, respectively.
Is the First Order also prejudiced in this way?
On one hand, they based themselves heavily on the Empire, and besides Snoke, they don't seem to employ any non-humans or have any non-human officers.
On the other hand, they are lead by Snoke, who doesn't seem to be human.
So to what degree were they prejudiced?
