The abnormal part is these activists bring up ancient negative definitions (that no one else has ever heard of) for words like "brown bag", when no one uses the 'bad' definition in daily practice, and try to ban it. If a word/phrase has evolved toward a positive definition, then its abnormal and regressive and wrong to try to bring back the negative definition and force people to stop using it. Why do they do it? For just the twitter points?
