Convergence theorists would suggest that a rally on Parliament Hill to oppose the war in Afghanistan is quite likely to change many people's attitudes toward the war.

Convergence theorists believe that individuals are unlikely to change their attitudes or behaviors through mass protests or rallies because they only attract like-minded individuals who are already supportive of the cause. Therefore, a rally on Parliament Hill to oppose the war in Afghanistan is unlikely to change many people's attitudes toward the war according to convergence theory.
