This is a more general question: If a person publishes what they know to be a material falsehood for the specific purpose of seeing a class of people they know to be telling the truth publicly maligned, is that libel/defamation against that class of people and/or the individuals within that class of people? Basically, is taqiyya a form of libel - whether it be Muslim, liberal, political, media etc taqiyya. lying for a cause with the intent of seeing your enemies FALSELY maligned?
The short answer to that question is no.
