MSNBC and Fox New are NOT news programs. They are admitted platforms for espousing ideologies. They, and others, selectively report and twist information to support their preferred views. You don't need to avoid them; just see them for what they are. To be knowledgeable, a person has to be exposed to information from a wide variety of sources, gather supported facts and make informed decisions. Consider facts and consider the source.
