I don't like the model of Falangist Spain except that for a dictatorship, it was relatively tolerant and Protestants and Jews could worship in freedom. This may have been a function of the government and society as a whole.
“I don’t like the model of Falangist Spain”
The Falangists never ruled Spain; Franco did. During the war they were forced to merge with the Carlists (their leader was killed in the beginning of the war), and were completely dominated by Franco.
While 300,000 involuntary adoptions sounds horrible in hindsight, the Communists slaughtered many more in their 3 year quest to force Stalinism on Spain’s people.
