"Religion really always boils down to pride and prejudice. If you can leave those behind, you will not compromise the religion.
If you still hold on to them, then almost anything can be a compromise of the religion."

Well, it seems you are an atheist. If yes, then I would say that no one exists without following a particular faith or ideology, even atheism is also a form of 'belief system' which is still to be proved to be true through 'empircal evidence'.
Not all religious people follow religion only because of certain indoctrination. I only follow because I find logic and rationale in my beliefs and hence I am what I am. Yet, I acknowledge and appreciate the different ideologies people hold. And I am told by my faith that if God wanted, he could have made all mankind as one people. Hence, he tells us to accept people from various backgrounds and work out on similarities and commonalities and not to behave or belief in a manner where I develop a pride that by virtue of my claim of being a Muslim, I am heaven-bound and everyone else is hell-bound.
The Noble Qur'an - Al-Hujurat 49:13
O mankind! We created you from a single (pair) of a male and a female, and made you into nations and tribes, that ye may know each other (not that ye may despise (each other). Verily the most honoured of you in the sight of Allah is (he who is) the most righteous of you. And Allah has full knowledge and is well acquainted (with all things).
