Religion, by itself, is normally not a qualifier when we refer to minorites, as that word normally implies an ethnic or racial minority. However, there are some religions with ethnicities tied to them, e.g. Jewish people, and Muslims, so the line can definitely become a bit blurred.
Jewish people are a minority in most places because of their ethnicity, not their religion. Muslims are often referred to as minorities in most places, because most Muslims are ethnically related, at least as far as the Western world is concerned.
Some also reuse the word minority interchangably to refer to religious minorities, political minorities, etc, which further blurs the line, but the most common use of the word is in reference to race or ethnicity.
Encapsulation kinda sounds like it could be a spell too. That’s 2/3 pillars of OOP.
