That would really bother me. I would ask her about it. As weird as it sounds some of the "unacceptable" adjectives for some groups is now acceptable, in my area, by the groups involved. For example, my husband is VERY French Canadian and some of what use to be considered and still is in some areas is now very acceptable and used by many French people including my husband and his family. Is this at all possible?? For a T to say derogatory things about certain groups would be really damaging to their career.
