4chan was founded to talk about anime. The original boards were focused on anime. As time went on, more and more boards were added, so that people who liked anime could talk about other topics they were interested in. Do you go to bodybuilding forums and complain about people talking about bodybuilding on the video games sub-forum?
You are the invader, my friend.
