Passage: Some forms of civil disobedience, such as illegal boycotts, refusals to pay taxes, draft dodging, distributed denial-of-service attacks, and sit-ins, make it more difficult for a system to function. In this way, they might be considered coercive. Brownlee notes that 'although civil disobedients are constrained in their use of coercion by their conscientious aim to engage in moral dialogue, nevertheless they may find it necessary to employ limited coercion in order to get their issue onto the table.'

Question: When large groups of people all boycott a system or don't pay taxes it can be considered?
coercive
