If there's a political motive in not choosing an American pope until now it's that for most of American history it wouldn't have granted them any influence over American politics. If there's a personal motive it's that until recently they felt insulted that America went for almost 200 years before finally electing a Catholic president.
Tangent: Protestantism is not a religion. The religion is called Christianity. I have seen this trend for quite a while of Protestants (or people born in Protestant countries) of referring to Christianity branches as religions. I find it very segregational. The whole point of all the branches is the same guy whose name begins with C.
But yes, given the state of America today, having an American pope will definitely be an interesting development in the context of many lobbying groups wishing for a vaticanised America.
It'd be like saying "Talking about Rust is segregational. It's just all branches of programming languages starting with C". Technically true, but not a useful distinction.
That analogy is not valid. Protestants argue that catholicism does christianism in a sloppy way, whereas they do it right. If you're going with a programming language analogy, it's like a C++ programmer arguing that onboarding cppcheck and --Wall --pedantic is the only acceptable way to work with C++, and everyone else is doing it wrong.
And of course they vary widely in rites, practices, and liturgy.
People think they are closer than they are. The difference between the protestant denominations, catholic denominations, mormans, jehovah's witnesses, etc are quite major and in a very real sense the separation between these different sects of Christianity are essentially only a few steps removed from the separation Islam has from Christianity.
