This reminds me of a story I no longer have the link to about how Democratic operatives were infiltrating Tea Party rallies and making them look bad (either racist, violent, or uneducated) by acting a bit over-the-top and getting media attention. This is why there can be no agreement on what the Tea Parties (or any other group) are about. One has to wonder if Republicans infiltrate environmental groups in order to vandalize SUVs to make them look bad and destroy their credibility (I have nothing to support this; I'm only speculating).
Just remember these articles the next time you speak with someone from a different political party, religion, or ethnic group. Beware of prejudice.
