No she was young and naive. The point is the MSM, which was even then controlled by the commies, put a good face on Castro. There was no fox news or internet back then to clarify things.
What I most dislike about discussing Cuban history and politics with Cuban Americans is the way they bring their family into the conversation, and then if one questions or contradicts what they say about their grandfather, they invariably become offended that one is contradicting thrir grandfather, and no further conversation is possible. In the hope that you are different, I will say that a person born in 1940 would have been 13 when Castro’s gang launched an insurrection against the Moncada barracks; old enough to hear and read about it, and draw conclusions
