Much of Rigoberta’s political education consists of understanding that while different institutions (such as the Guatemalan army and the Catholic Church) might be politically repressive, not all of their individual members are bad. Rigoberta’s decision to learn Spanish is tied to her awareness that one means to fight an unfair system is to attack it from within, by using some of its weapons. In this case, she’s using Spanish, which has historically been used to trick and oppress poor Indians who don’t speak the language.
