To protest or march in opposition to another protest or demonstration; to hold a counter-protest.
From counter- (against) + demonstrate (to protest publicly or show). Demonstrate comes from Latin demonstrare (to point out). This verb emerged in the 20th century to describe the modern practice of organizing opposing protests.
The rise of 'counterdemonstrations' reveals how democratic societies literally put opposing viewpoints on the street at the same time—it's protest culture becoming more sophisticated, where the counterdemonstration itself becomes part of the discourse.
