Comment: I find those who chant do so because they either have such a slim argument that they don't want to be drawn into it, or because they lack the mental prowess to mount their argument in a rational manner.  It is for that reason that the "Lock her up," chant is offensive.  

I should point out too that the main perpetrators of the chanting phenomenon are unionists, "Hey, Hey  Ho, Ho.  Fill-in-the-blank has got to go!"   Clever eh?   The "progressives" particularly the enviro-nuts, are no better,  “U.G.L.Y.  Corporate scum you cheat you lie.  You UGLY, uh, uh, you UGLY.”   That intellectual gem and many others are found on the website tarsandsblockade.org

Chanting has no place in rational debate, none.
