Will somebody please explain to me...

...why there are so many stupid people running around loose in this country?  I really want to know.  Don't they KNOW they are stupid?  Do they think before they say or do anything?  I mean, really?  Is it just me?  I am at the point now where I don't even pay attention to a person once I have determined they are stupid.  What ever happened to COMMON SENSE?...  FUCK!  If I have to deal with one more slack-jawed, glass-eyed, finger up their nose, retard I'm gonna go ballistic!
