You seem to be confused. 4chan is a collection of dedicated-topic imageboards, with the added feature of anonymity allowing people to express themselves without being concerned about the identity of the poster, but the quality (or lack thereof) of the post. I suspect you're post-/pol/, mid-20s, and think of 4chan as your anonymous autistic social network, but who you are isn't really important. Most memes are specific to the boards they are from. Containment boards are intended to contain unwanted posts. There are plenty of /a/nons, /g/entlemen, fa/tg/uys etc who never or rarely venture outside their boards and have no interest in your social network meme knowledge qualifications.
Judge the post, not the poster. Or don't. You're on 4chan after all, it's your choice.
