By the way, 30'000 dead is way off the mark.
The clergy alone lost 8000 Priests and Nuns to Communist murder gangs,
True. 30,000 is a huge undercounting of those killed during the civil war in Spain. Both sides comitted atrocities on their opponents, but the main difference between Franco's Fascists, sorry "Nationalists" is they had a policy of systematic extermination (and genocide when it came to the Basques), whereas the Repblican atrocities were carried out more in the "heat of the moment" and as retaliation and revenge against Nationalist atrocities.
Communists massacred people even before 1936.
In the years prior they regularly murdered priests and nuns. See the massacre of Galicia.
The Communsiss of the 1930's were basically like ISIS. Brutal and macabre.
They ofen took photos of themselves digging up graves and abusing the corpse.
Not all Basques supported the Reds by the way. The Basque region was one of the first to defeat Communism.
