Well, I never got to be a teenager and an Objectivist. I got to be a gifted teenager and an egoist though, and the problems teenage Objectivists are facing are not just because they don't understand the philosophy fully and seem religious.
Sorry to burst your bubble, but this sounds nothing like (rational) egoism, or Objectivism that I know (or want to know.)
All I've seen you express is petulant anger at everyone else - the fundamental definition of altruism, other-ism.
Know, and judge yourself, I'd suggest, before you take on the world.
Finding fault with everything else is objectively untrue - therefore, irrational - not to add, personally harmful.
Egoism leads 'naturally' to respect and good-will, if practised assiduously.
I'm sorry to see you heading in the opposite direction.
