The grandson of Argentinian revolutionary Che Guevara, he grew up in the upper crust of post-revolutionary Cuban society, but soon became disillusioned with the government of Fidel Castro.
After his mother's death, he went into exile in Mexico, where he worked as a writer for Proceso, penning criticisms of the Cuban government from a left-wing anarchist perspective.
[1][5] During his teenage years, he came to admire his late grandfather, although he also struggled with the expectation to live up to Che's legacy, as Cubans told him "how to behave, what to do and what to say".
[1][2][4][6] As he grew older, Sánchez Guevara became increasingly disillusioned with the government of Fidel Castro, which he likened to a monarchy, due to its repression of dissident activists and artists.
[1] By the time he turned 21, Sánchez Guevara's mother was dying of cancer in a Havana hospital, where the two discussed the state of the Cuban revolution.
He further denounced "the criminalisation of difference, the means of persecution of homosexuals, hippies, free thinkers, trade unionists and poets" and the installation of "a socialist bourgeoisie".
