Why are you so stupid?

Hey, anyone knows why most 4chan users are so damn stupid? I can't figure it out, I have been here for a long time and there have been really awesome discussion, but most of the time all I see is bland stupidity. I'm not even talking about /b/ stupidity, I mean the real, ignorant, retarded kind of stupidity.

Atleast most of the text boards are safe. Not enough easy amusement to make those teenagers with attention span of a hyperactive CHICKEN stay.
But fact is, communities CHANGE. 4chan is fucking ANCIENT by internet terms and has grown bacterial infection on brain stem during the long years, so it'd be a miracle worth of a god for it not to change.
So sit back, enjoy the chaos and stupidity (or troll the hell out of 'newfags'), and wait for 4chan to spiral to whatever hellhole it once spawned out of. Collect your "friends" (on MY /b/? It's more likely than you think) and build a circle or two with people of the same mental wavelength. 4chan has grown too large to accomodate a single type of people, so get used to people appearing to be truly mentally (and physically) retarded. Who knows, maybe some of those idiots will create something funny.
