There are several lines of Minsc and Viconia for example: "i'm born of a noble race" "i pity ou for your short life span" or "you foolme once, shame on you, you foolme twice, watch it! i'm huge!" "there's strenght in numbers aind i'm two or three at least". i played a lot with imoen and never one time she said "huh, your're a queer fellow" or "i care not". xzar is problably the most affected by this because he never states that he want the infravision of elves by removing their eyes. these among others, wich i dont recall in that exact moment. these lines are never said for the cited npcs in BGEE
i bealive that beamdog retired them because they consideres some of these offensive for mature children or with innapropriate language/or tendencies, intolerable in modern days, but acceptable in a world 20 years ago.
