Also, it is this same conservative Evangelical Christian movement that is sharing The Gospel with the lost in Brazil and seeing their numbers grow. I believe the attempt to associate these Bible believing Christians with the old state churches of the Reformation is just an attempt to confuse the issue and try to make the Roman Catholic Church look conservative.
It's as simple as that.
American culture is garbage and wherever it establishes itself Protestantism grows in lock step because Protestantism always digests and rationalizes whichever portions of the garbage it needs to keep drawing in the wallets.
None of these "good Christian" Protestant churches are ever going to start focusing on what they know will send their members elsewhere no matter how clearly it's evil and a sin. There won't be a series of sermons by any of the "Evangelical Christian" self-appointed "pastors" focused on the fact that contraception is abortion and abortion is murder. All the self-appointed shepherds know their crowds and membership would dwindle to nothing the same way membership in Fundamentalist churches that hung on to preaching against rock n' roll, dancing, and drinking beer, a bit too long dwindled to nothing.
The only real doctrine the vast majority of Protestants outside of the SBC have is, "go along to get along".
