Protestants in South America are much more of a tool of American imperialism than Catholicism at the moment due to the history of liberation theology, etc. Evangelicals in particular have strong ties with doctrinal shifts in their American counterparts, so they tend to follow arguments on particularly American shit. They also import evangelical teachers from America as if they are God, and reject the history of Christianity generally unlike Catholics.

There’s a much longer answer here about class interests, prosperity gospel, and pentecostalism, but I think the above is generally good.
