The actions of Freyre as a public intellectual are rather controversial. Labeled as a communist in the 1930s, he later moved to the political Right. He supported Portugal's Salazar government in the 1950s, and after 1964, defended the military dictatorship of Brazil's Humberto Castelo Branco. Freyre is considered to be the "father" of lusotropicalism: the theory whereby miscegenation had been a positive force in Brazil. "Miscegenation" at that time tended to be viewed in a negative way, as in the theories of Eugen Fischer and Charles Davenport.
