The current pope is overturning hundreds of years of catholic doctrine. He's not a benchmark of a traditional Christian. Also, most American Christians aren't catholic.

Eh, no, for decades now the Catholic Church has been pro science and accepting scientific theories like Theory of Evolution, Big Bang theory, etc.

That's not any of the stuff I'm talking about. Francis is, by far, the most outspoken supporter of homosexuality in recent papal history. Francis changed church policy in favor of divorces and annulments. He's also made many modern-liberal-friendly statements on abortion, environmental politics, economic inequality, and extra Ecclesiam nulla salus. He's very obviously retargeting church policy/optics in favor of a more liberal market. My guess is he's trying to pick up a bunch of atheist-by-birth millenials in the US and EU who tend to follow these politics.
