During a post-game press conference on Aug. 26 -- the day he refused to stand for the National Anthem at Levi's Stadium and later complained about U.S. "oppression" -- San Francisco 49ers quarterback Colin Kaepernick wore a Malcolm X cap and a t-shirt with photos of Communist dictator Fidel Castro, whose totalitarian regime is responsible for the murder of at least 73,000 people.

The t-shirt's photos show the Communist Castro meeting with the Muslim Malcolm X at the Theresa Hotel in September 1960. During that meeting, Castro, who was allied with the brutal Soviet Union, castigated the United States for "aggression" and "imperialism."

"I am not going to stand up to show pride in a flag for a country [United States] that oppresses black people and people of color," Kaepernick told the NFL after the game last Friday. "To me, this is bigger than football and it would be selfish on my part to look the other way. There are bodies in the street and people getting paid leave and getting away with murder."

As CNSNews.com has reported, the Communist regime of Cuba has killed an estimated 73,000 people since dictator Fidel Castro seized power in 1959.

Ray Walser, Ph.D., a senior policy analyst for Latin America at the Heritage Foundation, has documented that after Castro took over, he "commenced maneuvering against liberals and democrats, breaking alliances and power sharing deals to solidify personal power and set Cuba on the path to Communist dictatorship."

“Although Castro promised democratic elections, none were ever held,” says Walser. “The free press was muzzled; judicial independence was lost.”

The U.S. State Department describes Cuba as a “totalitarian communist state; current government assumed power by force on January 1, 1959.” There is only one political party allowed in Cuba, the Cuban Communist Party (PCC).

According to the Black Book of Communism, one of the most authoritative books on communist atrocities, and published by Harvard University Press, shortly after taking power Fidel Castro organized an extensive security apparatus.

His younger brother, Raul Castro, the current dictator of Cuba, “reinstated military tribunals, and soon the firing squad became a judicial weapon.” Che Guevara, commercialized on t-shirts today, was Fidel Castro's chief executioner and architect of Cuba's slave labor camps.

The first security group was called the State Security Department, and its nickname was the “Red Gestapo,” reports the Black Book of Communism. The Red Gestapo hunted down Castro’s enemies and established forced-labor camps.

Malcolm X was a radical Muslim who initally was active for many years with the Nationa of Islam. He later broke with the group, became a Sunni Muslim, and promoted Pan-Africanism. Malcolm X was assassinated in New York City by three members of the Nation of Islam in February 1965.
