Object Oriented Programming

As a novice programmer and as someone who started learning programming with C, OOP just seems annoying to me. Seems as though it's easier to accomplish the same tasks without it. Is it actually necessary to learn it?

public/private is good for automated documentation systems.  Users of your classes don't want to browse a fuckton of internal circuitry, they want a clean API so they can get shit done instead of looking through stuff they don't need for ages.  Good, competent users who demand that complexity and side effects be documented.
I don't see a lot of objections to internal functions in modules like non-exported stuff in Haskell.  Even Perl has export lists.  Private methods are like that, only for classes.
It doesn't make a lot sense for classes like Point, Circle, HelloWorld though, that's why it keeps being brought up.  It does have a use in real world.
