There's a common axiom that when accusations start getting thrown around, the accusers are often likely to project their guilt onto others and be engaging in exactly the kind of wrongdoing they decry. This seems to be proven very true by recent accusations from the left that protests against health care legislation were inauthentic "astroturfing" bought and paid for by the health care and insurance industries.
First they attempted to discredit the protests by describing generally well behaved protesters as an "angry mob" and ultimately as neo-Nazis and white supremacists based on distortions and the scantiest imaginable evidence, such as Nancy Pelosi seeing a sign with a swastika with a cross through it — indicating opposition to national socialism — and claiming that this meant the bearer was a nazi. This strategy fell apart when the extensive video of the protests made very clear that the protesters were peaceful and generally well-behaved despite the occasional passionate outburst. It even created the opportunity for humor at the expense of the Democrats with responses like the popular "I am the Mob" video.
The next response from the Democrats was to send in thugs to intimidate, assault and exclude anyone with a dissenting optinion who tried to attend a townhall meeting so that audiences would only ask approved questions and protesters would be kept out or scared away. Within a matter of days, union members and ACORN activists in matching shirts with identical printed signs were confronting grassroots protesters at every townhall. Now it has been revealed that these pro-health care advocates are not exactly what they seem. In fact, they are exactly what the left wrongly accused the grassroots protesters of being, a paid rent-a-mob made up of hired thugs an shills.
