At http://www.lpedia.org/Uses_Of_Platform_To_Attack_LP I "document instances in which the LP Platform was used in front of significantly-sized audiences to attack or embarrass the LP as too extreme". I still haven't seen such an attack since the 2008 platform was adopted.
Marc Montoni thinks he has found a counter-example at http://reddiva.wordpress.com/2010/01/11/why-libertarianism-is-just-plain-wrong/.
Montoni needs to re-read the part about "significantly-sized audiences". Alexa says that this "Red Diva" blog doesn't even have as much audience reach as my own modest blog.
Sorry, Marc. Swing and a miss.
