What does this mean?  I can’t really tell.  Is it a spelling lesson?  Is it trying to make some political point?  There’s no context in which to understand what the political point might be, so I guess it means whatever the reader wants it to mean.  All I know is that as an American, I will fight to the death defending your right to put a dumb bumper sticker on your car.  And when I say “fight to the death,” I mean that in the metaphorical sense.  If it came to actual death, I might not feel that strongly about it.  The fact is, though, if you have FREEDOM, you must also by necessity have FREE DUMB, whatever that is.  The freedom to be dumb is not free.
