These people singing the praises of Castro and weeping over the death of that tyrant should visit Baguanos or one of the other rural villages in Cuba and ask the locals there what they thought of him.
His atrocities are well- known.
Cuba is such a shining star with their universal health care and highly educated populace, thousands rig up floatation devices and risk their lives in shark infested waters to row 90 miles north so they could get to the US and reduce their standard of living.
I don't know what these people are smoking, but I want some. 
I went to a school as a kid in which the custodian was a refugee from Cuba. He was so desperate to get away from that "SHining star" that he hijacked a tour boat to get to America.
Another, more notable Cuban refugee was Antonio Prohias, the cartoonist best known for creating the 'Spy vs. Spy' comic strip seen in Mad Magazine. He was a respected political cartoonist for a respected Cuban newspaper, but he was fired for making cartoons that made fun of Castro (Not that he was fond of Batista, either) and Communism as a whole, and would have been arrested for the same reason had he not fled to America, where he was eventually hired by Mad.
