Michelle Malkin has a great piece on the left's long history of fake stories of victimhood.
The way it has always worked is that they put out the story, the MSM dutifully reports it as fact with none of what was once called "investigative journalism" (so quaint!), and then when the truth finally comes out, it's only so much paper. The lie stands.
Just take a gander at this partial list (several pages long) of faked hate crimes that have taken place the last few years, at Sweetness and Light.
Of course racism and homophobia gets a pass when indulged in by the left. In that case, it's for a good cause.
Malkin on the recent supposed racism and violence of the Tea Partiers:
... the claims that Tea Party activists shouted "nigger" at black House Democrats remain uncorroborated. The coffin reportedly left outside Missouri Democratic Rep. Russ Carnahan's home was used in a prayer vigil by pro-life activists in St. Louis protesting the phony Demcare abortion-funding ban in Obama's deal-cutting executive order. Videotape of a supposed intentional spitting incident targeting Missouri Democratic Rep. Emanuel Cleaver at the Capitol shows no such thing. Cleaver himself backed off the claim a few days later. He described his heckler to The Washington Post in more passive terms as "the man who allowed his saliva to hit my face." Slovenliness equals terrorism!
The FBI is now investigating the most serious allegation -- that Tea Party activists in Virginia are somehow responsible for a cut gas line at the home of Democratic Rep. Tom Perriello's brother. But instead of waiting for the outcome of that probe, liberal pundits have enshrined the claim as conclusive evidence of the Tea Party reign of terror.
The truth doesn't matter though, because the left sees a larger truth: they KNOW anyone not committed to socialism is hateful, racist and violent.
