When you can't say anything intelligent, resort to Ad-hominem arguments.
 

From time to time I get a rabid response to something on the www.energyadvocate.com website.  The newest exercise in creative spelling came with the subject heading Ethanol and says,

I'll type s l o w l y here so you'll be able to understand this.

YOUR [sic] AN IDIOT!..... y o u  a r e  a n  i d i o t !

I think that will be as much as you can possibly handle at this point. If not, get a  d i c t i o n a i r y [sic].

Our response:  Any chance you're high on ethanol?
