The Left is so self righteous they think they can get away with anything and unfortunately, they usually do. Remember their battle cry "By any means necessary"

CONFIRMED: Left Wing Plant at Houston Pro-Zimmerman Rally Is Far Left Activist

LEFTIST PLANT INFILTRATES HOUSTON PRO-ZIMMERMAN RALLY– 
Liberal Media runs with it

A photo from the Houston pro-Zimmerman counter-rally of the NBPP anti-Zimmerman rally picked up by the AP shows a woman holding a sign that read, “Racist & Proud.”

That looked incongruent with the other reports from the pro-Zimmerman side.
The Houston Chronicle identified her as Renee Vaughan:

One woman in the Zimmerman group held a sign that said, “We’re racist & proud.”

Austin resident Renee Vaughan echoed the sign’s ugly sentiments by yelling, “We’re racist. We’re proud. We’re better because we’re white,” at the Martin group as they passed, according to the Chronicle.

The act to smear the Zimmerman supporters as racists with a leftist plant worked as the photo and comment was picked up and spread worldwide.

Scanning the internet we found that a “Renee Vaughn” from Austin worked for a far left environmental group, the Texas Campaign for the Environment.

Renee even has her photo linked to a far left environmental website.

Here are two photos of Renee Vaughan side-by-side:

Here’s another shot of Renee at a leadership event for community organizing.
She’s standing up front in the wild dress.

It looks like Renee Vaughan was definitely a racist leftist plant at the Houston rally.

This is how the left operates, folks. This time they got busted.

UPDATE: Thanks to reader Karadion – here is a photo of Renee Vaughan with the same sunglasses she wore while holding the racist sign at the pro-Zimmerman rally.

Yup. They’re the same sunglasses.

UPDATE: Brandon Darby interviewed Renee Vaughan at the rally. She told him her sign means that “there are people here who are racist and apparently think that’s OK. I’m not one of them. I’m being sarcastic.”
