He has acknowledged the racial prejudice in ARR when he chastises his men for "abandoning" Rhitahtyn and his first assumption was that it was because of his birth. Another detail is gaius' legion likely encouraged other races more than most so he at least attempted to build his legion around his values but as we've been shown many garleans within that chain of command abuse their position over 'lesser' races behind gaius' back.
