(A) condemning the condemners

Explanation:

Erving Goffman defined two stages of behavior i.e front stage behavior and backstage behavior. Front stage behavior is visible to the audience and is a part of the performance whereas backstage behavior is not meant for the audience and it happens backstage where no one is present to watch the behavior. By front stage, he meant the behavior we carry-out for the outside world including rude, smart, smooth, and intellectual, etc whereas backstage behaviors refer to the real self which we keep for our-self i.e the real self of the personality.
