Left’s Playbook: Calling Everyone ‘Racist’ the ‘Most Effective Tool’. By Andrew Breitbart in 2012.

One of the most effective tactics that the left has is the ability to accuse its opponents of “being a racist.”

It’s an impossible negative to dispel. It immediately puts somebody on the defensive, and it sends a message to the audience: you shouldn’t take seriously what’s coming out of that person’s mouth, because they’ve been degraded as being a racist.

In the era of my conservatism, which is the last 20 years of my life, I’ve tried to make the argument that that’s an affirmation of precisely the opposite: that if, in this country, being accused of [being] a racist is the worst thing that causes people to shut up, doesn’t that mean that racism has been dispelled to a huge degree? …

It is used because those who wield it know how effective it is. That is the primary reason. It is the most effective tool that the Democrat-media complex has.
