I have had enough of this shit.

The Batista regime sold the people of Cuba to the Mafia or left them to starve on the streets. It oppressed, imprisoned, executed, and otherwise dispossessed and killed to a greater extent than the Castro regime. Remember the "10 to 1" order that Batista gave? If your measure of legitimacy is simply the alleged "oppression" the Castro regime was at least no worse and probably better than the Batista regime.

The people who fled Cuba were those who had, prior to the successful and popularly supported Cuban rebellion, oppressed the ordinary Cuban. Many went straight back into US mafia organisations or clones thereof. As Castro said - those he executed were the criminals who deserved execution.

On the other hand, Castro gave Cuba freedom from starvation, freedom from homelessness, freedom from illiteracy, and health. A damned good deal for Cuba. And a similar revolution would be a damned good deal for the USA and the UK, where the oligolists conspire to starve and exterminate the less advantaged.
