"Mexican food was also associated with anarchism and union organizing. Tamale vendors were blamed for the Christmas Day Riot of 1913, when police raided a labor rally in Los Angeles Plaza. Milam Plaza in San Antonio, where the chili queens worked in the 1920s, was a prominent recruiting ground for migrant workers. Customers could eat their chili while listening to impassioned speeches by anarcho-syndicalists of the [Industrial] Workers of the World and the Partido Liberal Mexicano."
