Pretty impressive that you got that far already!
You're just writing that to provoke me, aren't you?
One of the things that most disgusts me about Franco and his cronies is the way they put the lie to everything they claimed to stand for during the civil war, almost literally from day one. They claimed to stand up for religion but murdered priests (if not as many as the other side), claimed to stand up for the family but used mass rape as a tactic, claimed to stand up for Spain but were happy to offer Hitler Spanish villages as target practice and to encourage their Moroccan irregulars to rape and pillage all over the place.
If the book isn't too blatantly biased, it could still be an interesting read - I don't dispute that the Second Republic had its ugly sides, or the "two evils" characterization. Just your choice of the lesser one.
