The media has been extremely biased for nearly as long as I can recall. The first time it became obvious to me was when they supported Castro to such an extent that I, a 9 year old kid, wanted to go to Cuba and fight Batista.
I was shocked when he began executing his opponents and made it clear what he really was.
I do believe they went to the most extreme during this last election. Often did not even try to hide their bias.
My husband told me that at his professional school there were jars to deposit money in to support Castro during that time. In his school!
