From an April 28 Washington Times editorial titled, “Angry, hateful, violent, extremist, liberals”:

Imagine a group of angry demonstrators toting swastika-festooned protest signs calling politicians Nazis, shouting obscenities and racial remarks and throwing rocks and bottles at police officers sent to keep order. No, these are not Tea Partiers. They are the mob that turned out last week to protest Arizona's new immigration-enforcement law. This group of liberal rowdies has been dubbed the Tequila Party.

For the most part, liberal media coverage overlooked all the leftist violence. Typical headlines described the protest as “mostly peaceful,” with media outlets avoiding details about why they had to use the qualifier “mostly.” Reporting a near-riot by the opponents of the Arizona law doesn't fit the dominant media storyline.

[...]

The Tea Partiers do not incite violence; they are salt-of-the-earth middle Americans who are desperately worried about the misguided policies and wrongheaded vision being promoted by President Obama and his congressional allies. Contrast them with the younger, less educated, lower income, angry, racially motivated mob that turned out in Phoenix. The Tequila Party and gangsters like them represent the core and the pride of the liberal base. If an angry, shouting mob throwing bottles at police is the face of contemporary liberalism, it's no wonder Americans are turning against them in droves.
