adultism 

If you believe adultism is right, you might as well thumb me down before going on.

1) The belief that adults are superior to minors. It is so widespread and common that most people don't even know adultism exists.

Corrupted scientists use junk science (incorrect scientific facts) to try and justify adultism. Unfortunately, it works.

Most people think pictures of an adult's brain and a teenager's brain can be compared to argue that adult's are superior in every way possible. -_-

Angela: May I participate in this homosexuality debate?

Adult: No, you are just 16 years old. Your brain is not developed enough to debate in this adult topic.

Angela: -_-

*and some more adultism*

Tom: Why can't I watch Family Guy, dad?

Dad: I want you to stay as innocent as possible throughout your childhood.

Tom: Epic fail!

Having to do grown up things like work a steady job to earn money to pay bills and break even every month because you were not born/ married into millions.
