Hope in mankind. HA! Mankind is a disgrace. You are too modest. Too optimistic. Read a history book, and you'll see that mankind has always tried to either control or kill one another. Humanity will never rise from this nature.

You're right, 4chan isn't /b/. But all other sections ACT like /b/. They are selfish, ignorant, arrogant, condescending, sadistic, stubborn, assholes.
