What's really sinister about all this is the MSM is going to keep pushing this particular Big Lie about talk radio, Fox News, and conservatives. And we've seen that they can have some success with the Big Lie--the whole bullshit line of argument about Sarah Palin's "experience" took root among among Republicans and Independents, and so did their general character assassination of her. Most of the time they're only talking to themselves--but sometimes not.
I'm going to type this because it can't be said often enough in the face of the Big Lie--conservative thought and crticism of regressive (ie, what they call "progressive") thought is mild and civil when compared to its liberal counterpart, and if any vitriolic speech is responsible for upticks in violence and Loughner's shooting rampage particularly, i'ts the almost unending hate-filled rhetoric of the Left.
I know we all know this, but it needs to be repeated frequently when faced with the Big Lie technique.
