Idiocy should not be rewarded.
My first impulse would be to shun and ignore these particular idiots, but they are so numerous and persistent that I don't know what else to do. Plus, their bongoes are really annoying. And loud. And let's not even start on the puppets and hygiene habits. So sadly, they will not be ignored, so more drastic measures are called for.
Here goes.
Anybody who seriously uses the expression "speak truth to power" should be shot; their families sold into slavery; their Peugot stripped of the fifty bumper stickers plastered on the back and then crushed into a cube and placed in a landfill (not recycled); their possessions sold; their animals slaughtered for fur and meat; and their land plowed under and salted so that nothing may grow there again.
This isn't prompted by anything really specific. Just a vague feeling of unease that welled up today into a solution.
It's only a suggestion. Discuss amongst yourselves.
