The public/secret dichotomy is false, the term 'front' is used in communist parlance as a euphemism for 'sector'. I'm not sure, if merged, what material from the Communist front article is to be added here? This article has a better passage on mass organizations (which needs referencing), but the Communist front article is 1) grossly US-centric and 2) filled with insinuatory wordings. It contains extremly little factual substance to be included here.
