Actually, SouthWest has a policy against offensive language, profanity, and such, and as I read the description of the shirt, it fit the policy for LANGUAGE, regardless of who the subject was. Their policy forbids the wearing of clothing with swearing or cursing and such on it. I'd say if the profanity filter here would catch it, they can forbid it from their planes. Don't like it? Don't fly SouthWest.
