Below is a flyer that has been created to drum up support for a protest. It purports to be a counter-demonstration to the Lehigh Valley Tea Party even though the LVTP had their rally the previous week with absolutely no plans to do a repeat. It's obvious focus is to demonize those who disagree with their point of view.
This "cry racist" tactic has been a moderately successful one for people trying to cripple the Tea Party movement. No one likes to be called a racist. Racism is ugly, irrational, and ungodly. But as time goes by and people get a chance to meet Tea Party members the lie is shown for what it is - an intellectually lazy way to "win" an argument by calling names.
Scroll down further and you'll see a marked-up version of this flyer, how it ought to be read with understanding. The original issue, children being trafficked across Mexico, is only secondary to the need for these groups to demonize their opponents. It does nothing to stop the smuggling of children, it only perpetuates it.
