This is simply false. The Spanish Civil War started in 1936 with Franco's fascist coup against a democratically elected government. Check your own ignorance before accusing others.
"The defeat in the elections and its consequences led to disenchantment with parliamentarism and radicalization within the Socialists. The increasing militancy within the Socialist workers was followed by Francisco Largo Caballero's adopting a revolutionary Marxist rhetoric which justified revolutionism as a way to combat rising fascism, uncharacteristic of European social democratic mainstream and the reformist traditions of the PSOE.[69] The CNT adopted a similar rhetoric in the wake of the elections, threatening with a revolution if "Fascist tendencies" would win the elections.[70] Open violence occurred in the streets of Spanish cities, and militancy continued to increase,[71] reflecting a movement towards radical upheaval, rather than peaceful means as solutions.[72] A small insurrection by anarchists occurred in December 1933 in response to CEDA's victory, in which around 100 people died.[73]
[...]
Fairly well armed revolutionaries managed to take the whole province of Asturias, murdering numerous policemen, clergymen and civilians, destroying religious buildings including churches, convents and part of the university at Oviedo.[75] Rebels in the occupied areas proclaimed revolution for the workers and abolished the existing currency.[76] The uprising was crushed in two weeks by the Spanish Navy and the Spanish Republican Army, the latter using mainly Moorish colonial troops from Spanish Morocco."
Anyhow, Franco was a fascist trash and allied with Hitler and Mussolini. Revolutionaries were mainly anarchists (NOT communists). In fact it's because of Stalin and the communists following him starting an infighting with the anarchists led to the fascist victory.
If the revolutionaries have won, Spain would have been an experimental socialist/anarchist republic. We don't know if ot would have been ended up like USSR. Maybe.
In 1968 though the flight was pretty much about fascism vs democracy.
Oh, last point: Torture is torture.
I tend to agree with that, because nothing shouts "experimental socialist/anarchist republic" like "murdering numerous policemen, clergymen and civilians, destroying religious buildings including churches, convents and part of the university".
