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.

Deciding what is a “branch” of a religion versus whats is an independent “religion” is more subjective than objective. This might become clearer if we move away from Christianity for a moment, and look at the same question for some non-Christian religions

Consider the southern Indian religious movement of Ayyavazhi - most people, both in India and outside it, consider it a branch/denomination/sect of Hinduism, including even many followers of Ayyavazhi - but some of its followers and leaders insist it is a separate Dharmic religion [0]. The question is (in part) political - Dravidian nationalists and Tamil nationalists are more likely to call it a separate religion, Indian nationalists (Congress) and Hindu nationalists (BJP) want to view it as part of Hinduism

Meanwhile, most people consider Buddhism, Jainism and Sikhism to be separate religions from Hinduism - but the British courts in India decided they were branches of Hinduism, a classification still followed by the Indian legal system to this day. Many Hindu nationalists promote the idea that these traditions are branches of Hinduism, even though most of the Indian followers of those religions reject the idea.

It is standard to classify the Alevis in Turkey as an Islamic sect - yet the Turkish government wants to insist on the idea they aren’t even a sect, just a “cultural movement”, to promote the fiction of a homogeneous Turkish Islam - but while some Alevis are fighting for government recognition as a separate sect of Islam, there is a movement among Alevis (Ishikism) which claims it is a separate pre-Islamic religion, and its Islamic content is just a superficial distraction (dissimulation) to prevent persecution. Meanwhile, many hardline Sunnis around the world agree that Alevis are a non-Islamic religion - and some of the most hardline Sunnis will even say that of mainstream Twelver Shi’a.

So, the boundary between “branch of a religion” and “separate independent religion” is more subjective (theological and political) than objective.

my cheap excuse is that Europeans learn en-uk ;-)

Every sect within a religion is going to argue that they are the ones doing it right and the others are either wrong or at least suboptimal depending on the state of inter-sect relations. I would peg the Protestants as C and the Catholics as C++ in this analogy, as the chief defining feature of protestantism is that they do not acknowledge the legitimacy of just about everybody who has ever claimed to speak on God's behalf past a certain point; thus, like C, their view of religion is inherently stagnant. They don't necessarily deny that God continues to interact with his creations, but they've realized that statistically speaking any given prophet or saint has an approximately 0.0 probability of actually conveying messages from God so they'll just stick with the ones that are so old that just about everybody [who calls themselves christian] already agrees on them. This is similar to the way that many C programmers are really C++ programmers who got tired of all the dumb new C++2x bullshit and just want to write computer programs.

Both the protestant religion and the C programming language have viewpoints that make sense given the histories of their respective subjects, but the major drawback of these viewpoints is that they have chosen to limit themselves to only iterating through new interpretations of old ideas; both of them are fundamentally incapable of innovation because being incapable of innovation is the fundamental core of their belief systems. Thus, if God ever really does try to leave the protestants a voicemail or if bjarne stroustrup ever does come up with an idea that isn't terrible and needlessly complicated, both the protestants and the C programmers will miss out on it.

I will not even attempt to speculate as to which programming languages should represent islam and judaism in this analogy because i do not want to die or have my account banned.
